vkQuake 1.31.3 Binaries

This is very likely the ultimate update of the 1.31 line, bringing some fixes from either Quakespasm or Ironwail.

Improvements:

• Library updates : vkQuake is now using mpg123 by default instead of mad for mp3 support.

Fixes:

• #740: Fix broken saves in Mjolnir
• #718: Fix MD5 models to support multi-meshes. Quake Remaster models were fine because mono-mesh, but other addons exist bringing multi-mesh MD5 models.
• Some smaller fixes here and there.

Please note: Windows 32bit binaries are not tested / not supported and are provided "as-is".

Windows binaries require the Microsoft Visual C++ Redistributable:
https://aka.ms/vs/17/release/vc_redist.x86.exe (32 bit)
https://aka.ms/vs/17/release/vc_redist.x64.exe (64 bit)

Linux AppImage requires at least glibc 2.31. Check with ldd --version if in doubt (any recent Linux distribution should easily satisfy this). FUSE must be enabled and available (see https://docs.appimage.org/user-guide/troubleshooting/fuse.html)
