Support "Split to Volumes" 7zip feature

[Kcchouette]

On 7zip, we can Split to Volumes the target file/folder we want to put in 7zip using -v

Here the documentation Parameters -v{Size}[b | k | m | g] Specifies volume sizes in Bytes, Kilobytes (1 Kilobyte = 1024 bytes), Megabytes (1 Megabyte = 1024 Kilobytes) or Gigabytes (1 Gigabyte = 1024 Megabytes). If you specify only {Size}, 7-zip will treat it as bytes.

It's possible to specify several values. Eg; 10k 15k 2m creates three volumes; 10KB, 15KB, and 2MB in size.

Thanks in advance

Maybe should you deactivate github-actions (bot) as:

• I won't comment every week
• it closes useful issue (eg Not all resources are released on close() method #88 Inefficient buffer handling #89)

@Kcchouette If you want to extract files such as data.7z.001 data.7z.002 data.7z.003, you can do it without py7zr modification as follows;

cat data.7z.001 data.7z.002 data.7z.003 > data.7z
py7zr x data.7z

You can also create sliced archives

split -a 3 -b 10k data.7z

You can find files data.7z.001 data.7z.002 data.7z.003

It is good chance for contributor to add command line option and add function described above in py7zr/cli.py.
For creation,

1. create archive.7z as ordinal but on temporary directory.
2. split archive into a several files with a specified size.

#134 is super simple implementation. Does it help @Kcchouette ?

[miurahr]

v0.7.2 with the feature as CLI is now released.

Thanks, it's exactly what I wanted
Maybe should you document that? https://py7zr.readthedocs.io/en/latest/py7zr.html#command-line-options

Document updated. I'd like to close.
