压缩游戏存档以降低空间使用并提升保存速度

原作者 @bluedoom(直到1.1.11) 和 @starfi5h(1.1.12)，本人继续更新以支持最新游戏版本。

Updates

1.2.2

• Fix #4, a bug caused by non-ASCII UTF-8 characters.
• Remove use of Harmony.UnpatchAll() to avoid warnings in BepInEx log.

1.2.1

• Simplified codes to display compression type and Decompress button on save/load UI, making CompressSave compatible with other MODs(like GalacticScale) which override UILoadGameWindow::OnSelectedChange().
• Add compression level -5 to -1 for zstd, which makes it working better than lz4(which is actually lz4hc used by lz4frame) now:
  • -5 gets faster compression speed than lz4 with still a little better compression ratio.
  • -1 has almost the same speed against lz4 with greater compression ratio.
  • Due to bug of r2modman UI which does not support negative integer, the config value of compression level is not limited any more.
• move native wrapper DLLs into x64 folder to avoid warning logs on loading BepInEx plugins.

1.2.0

• Match game version 0.9.27.15033.
• Add new compression type: zstd (a bit slower but get better compression ratio than lz4).
• Add config to set compression type and level(Don't use high compression levels for zstd as they are very slow).
• Hide decompress button for normal save files.
• Optimize native dlls for other compression library support:
  • Unified naming rules for filenames and export functions.
  • Add compression level support.

• Fix Sandbox info on Save/Load Panel.
• Fix DLL version info.
