3.0 rc2 - update win binaries

[thezoggy]

placeholder to check on included binaries before we roll the next update. mainly focused on windows (just what i have access to at the moment, but most likely also applies to osx inclusion)

unrar 5.91 (RC1 came with 5.90)
https://www.rarlab.com/rarnew.htm

   Version 5.91

   1. Dialogs are centered inside of WinRAR window similarly to WinRAR 5.80
      and not inside of entire screen as in WinRAR 5.90.

   2. When editing an archived file with external software, extra measures
      are taken to reduce the probability of interfering with editor
      and opening its temporary files while editor still may need them.
   
   3. "Version to extract" field in archive properties opened from
      Windows Explorer context menu provides the additional information
      about ZIP compression and encryption algorithms, such as LZMA or AES.
      This information was already available in WinRAR "Info" command,
      but missed in archive information accessible from Windows Explorer.

   4. "MS DOS" and "Unix" host OS types are recognized and included
      for LZH archives in "Info" command. Previously the host OS field
      was always "Unknown" for LZH archive format.

   5. Files created by external editor and matching "Settings/Viewer/
      Ignore modifications for" masks are never added to archive.
      Previously WinRAR still added them if some file not matching
      these masks was also created or modified.
   
   6. Bugs fixed:

      a) empty file names were displayed inside of some Unix LZH archives;

      b) WinRAR could not process more than 999 7z volumes in a single set;
      
      c) if user cancelled the user account control prompt after changing
         "Integrate WinRAR into shell" option, a new state of this option
         was displayed in "Settings" dialog, even though the actual state
         of shell integration was not modified;

      d) the main window size could be too small on the first run after
         clean install with no previous WinRAR version present;

      e) WinRAR could stop responding after editing an archived file
         with external software in Windows 10 version 2004.

multipar 1.3.1.0 (RC1 came with 1.3.0.7)
https://github.com/Yutaka-Sawada/MultiPar

[ Changes from 1.3.0.7 to 1.3.1.0 ]

    GUI update

Change
It supports different output style of new PAR2 client.

    PAR2 client update

New
At creation, 1-pass processing File IO is possible for source files on HDD.

Change
GPU encoder will write recovery data on files after finish encoding.
On Windows 7 or later, it may recognize SSD for faster processing.

Bug fix
It might fail to allocate memory, when free memory was few or fragmented.

7zip 20? (RC1 came with 19.00)
https://www.7-zip.org/

20.02 alpha 2020-08-08 
------------------------- 
- The default number of LZMA2 chunks per solid block in 7z archive was increased to 64. It allows to increase the compression speed for big 7z archives, if there is a big number of CPU cores and threads. 
- The speed of PPMd compressing/decompressing was increased for 7z/ZIP/RAR archives. 
- The new -ssp switch. If the switch -ssp is specified, 7-Zip doesn't allow the system to modify "Last Access Time" property of source files for archiving and hashing operations. 
- Some bugs were fixed. 
- New localization: Swahili.

20.00 alpha    2020-02-06
-------------------------
- 7-Zip now supports new optional match finders for LZMA/LZMA2 compression: bt5 and hc5, 
  that can work faster than bt4 and hc4 match finders for the data with big redundancy.
- The compression ratio was improved for Fast and Fastest compression levels with the 
  following default settings:
   - Fastest level (-mx1) : hc5 match finder with 256 KB dictionary.
   - Fast    level (-mx3) : hc5 match finder with 4 MB dictionary.
- Minor speed optimizations in multithreaded LZMA/LZMA2 compression for Normal/Maximum/Ultra 
  compression levels.
- bzip2 decoding code was updated to support bzip2 archives, created by lbzip2 program.
- Some bugs were fixed.
- New localization: Turkmen.


19.02 alpha    2019-09-05
-------------------------
- 7-Zip now can unpack files encoded with Base64 encoding (b64 filename extension).
- 7-Zip now can use new x86/x64 hardware instructions for SHA-1 and SHA-256, supported
  by AMD Ryzen and latest Intel CPUs: Ice Lake and Goldmont.
  It increases
    - the speed of SHA-1/SHA-256 hash value calculation, 
    - the speed of encryption/decryption in zip AES, 
    - the speed of key derivation for encryption/decryption in 7z/zip/rar archives.
- The speed of zip AES encryption and 7z/zip/rar AES decryption was increased with 
  the following improvements:
   - 7-Zip now can use new x86/x64 VAES (AVX Vector AES) instructions, supported by 
     Intel Ice Lake CPU. 
   - The existing code of x86/x64 AES-NI was improved also.
- There is 2% speed optimization in 7-Zip benchmark's decompression.
- Some bugs were fixed.

Since none of these contain security fixes, I will wait untill 3.0.1 before updating them.
Want to use the Release Candidate to really change as little as possible.
Particularly the Multipar update seems to suggest that the output style changed, so a major code change might be needed or maybe it's subtle and we might miss it: It supports different output style of new PAR2 client.

[Safihre]

Will close and check for updates when releasing 3.0.1.

Just to bump this again for next minor release
