* Remove unused C versions of gu functions which will conflict with ASM versions under the new build system
This is a holdover from the decomp, as it must support older libultra versions which used these functions; as we're basing this project off of the final 2.0L, they gotta go
* Comment out bugged unused debug code
Will be removed completely by #12 soon enough anyway, but this will break CI if I don't remove this
* C++ fix in ultra64.h
* New build system
Based off my personal "template" featuring makedepend and support for automatically building and installing all 3 library versions, along with colors
Still needs cleanup to make sure I've brought over everything from the previous makefile
* Fix clang_format
* CI fixes to account for the non-decomp build system
* Remove old makefile
* Remove decomp tools
* Accidentally removed format checker
* Change VERSION to TARGET
* Fix install target by removing unused files and bring back ZSort header
* Fix CI typo
* gzsort header removed, I will figure out how to add it in modsdk later
* just copy the whole PR folder instead and remove install.mk, unnecessary
* SDK installation shall be handled seperately
* Remove RMON and a few leftover KMC things
* Remove MODERN_CC, as everyone is gonna be building this on a modern compiler anyway
