0.20.4 - Cyberpunk Edition

As the name implies, this update is specifically meant for Cyberpunk 2077. Mainly it adds some early support for "selective downloads" so only needed language packs can be installed. This will hopefully be expanded to other games in the future (although only ~3 actually support it).

Note that changing installed language packs after installation is currently not really supported, although manually changing the config file and then running a repair or installing an update (if available) will download additional ones, no longer required files will not be deleted when updating or repairing.

Changes:

• Basic support for selective downloads of Cyberpunk 2077 language packs was added
• max_workers can now be configured via the configuration file
• Minor bugfixes
