Feature request - Load all supported files from zip/folder

[buvk]

Hello, I was wondering if it would be possible to implement a feature where if a zip file or a folder is loaded via "-file", all supported files in the archive/folder are loaded.

For example, if btsx_e1.zip (containing btsx_e1.deh, btsx_e1a.wad and btsx_e1b.wad) is loaded via "-file", crispy-doom would essentially launch using the following parameters: -deh "btsx_e1.deh" -file "btsx_e1a.wad" "btsx_e1b.wad"
