[Add Feature] Check Mod-File integrity aka force redownload mod files
To help with faulty downloadet mod-packages enable in the debug section the option to force redownload mod-packages also have an option to verify MD5-checksum in cache against online packages to see if a mod-file is faulty or tempered with.
All of this is already happening before extracting the mod files (and has been the case since SMM v2.1.0 in July 2020). So that is every time you install/remove/enable/disable a mod, turn mods off/on, or change the profile.
However, there is no check currently for the extracted mod files, since their hash is not stored on ficsit.app, just the hash of the zip as a whole.
I know but I got an SMM crash and SMM wouldn't check the check-sum of the in-cache mod-packages so there were faulty (bc the crash).
