Create Calamus intermediaries for Classic and Pre-Classic versions

[Copetan]

If I understand correctly, the reason why we haven't made Calamus mappings for these versions is due to issues with Stitch parsing obfuscated vs unobfuscated names. Ideas on how to fix this have been mentioned Discord, but they have just been scattered conversations up to now, so hopefully people can use this issue (and the respective issue that should be made on the Stich repository) to discuss about this. This issue will be edited as more information comes up.

To give some context on Stitch: it tries to figure out which elements are obfuscated and which aren't, and it will only generate an intermediary name for obfuscated elements. For modern versions this works fine, as the only unobfuscated elements are a) inherited from the JDK or another library b) the main class of the game, and these elements should indeed not get intermediary names. However, it gets tricky for early versions of classic, since they appear to be only partially obfuscated. In previous discussions we agreed that we wanted to generate intermediary names for these elements anyway, but that means we need to update Stitch to ignore obfuscation checks.

progress on this: mappings have been generated for gen2 - will keep this open until that's stable
