- Decompile and patch `texture.gc` for PC - Improve decompiler when offset doesn't fit in immediate (for types larger than 8k and some scratchpad accesses) - Fix symbol->string issues in both jak 1 and 2 - Fix bug with VIF interrupt used to profile VU code (hooked up to OpenGLRenderer BucketRenderers in PC port) - Support `~o` in `format`. - Uncomment stuff in `merc.gc` that now works!  fixes https://github.com/open-goal/jak-project/issues/1850
