Update dependency Lizzy to 3.0.1, change M3U text encoding to ISO-8859-1

[Borewit]

⚠️ Warning: may have issues reading M3U generated with previous versions as the encoding changed from UTF-8 to ISO-8859-1.

Resolves #223

Playlist previously saved as .m3u maybe causing character encoding issues. Best to rename those to .m3u8 and load with liftFix() and save as .m3u if required.

Saving a playlist m3u8 is broken, it saves as m3u.

Is it imperative to rename the *.m3u playlist file extensions to the *.m3u8 file extension outside listFix() before they get added to the Playlist Directories (PD) pane? Because, the file extension can also be changed to *.m3u8 while the *,m3u files are already present in the PD. If the file extension gets renamed from *.m3u to *.m3u8 inside the listFix() PD, instead of renaming it with an external app, does it make any difference, or pose a potential risk?

Review: listFix() 3.0.1-2_4cb01be

Steps:

1. Two sets of playlist files were tested. Each set consisted of two playlist files — one with the *.m3u file extension, and one with the *.m3u8 file extension. The two files in each set were mirrors of each other.
2. One set was renamed with an external app, and one set was renamed while present inside the listFix() Playlist Directories pane.
3. These 4 files were opened in the Editor simultaneously.
4. All 4 files were fully repaired in one operation.
5. The playlist repairs concluded successfully, and the results were consequently saved.
6. No further testing was done.

The safest option is to rename playlists outside listFix(). You might as well simply repair broken playlists. If the playlist turns green there is no issue. The only difference is how special characters are encoded.

Yes, that's exactly how it's usually done. Rarely, if ever, find it necessary for another approach. Other user perspectives may differ though, and it's fitting to have that support in listFix() on standby.
