Oh lila LOVESSS breaking main RIGHT SCUT?

I tested this and it works and the code is simple enough.

On an somewhat unrelated note, the exportGeolayoutArmature have camera arguments with some esoteric uses that are lost to time and never used. This should be cleaned up at some point.

When you call exportGeolayoutObjectBinaryBank0 it still has the camera argument present. Same with exportGeolayoutObjectBinary and exportGeolayoutObjectC

Traceback (most recent call last):
  File "C:\Users\scut\Desktop\fast64-main\addons\fast64\fast64_internal\sm64\sm64_objects.py", line 1854, in execute
    self.execute_gfx(props, context, obj, index)
  File "C:\Users\scut\Desktop\fast64-main\addons\fast64\fast64_internal\sm64\sm64_objects.py", line 1843, in execute_gfx
    raise Exception(e)
Exception: Error: exportGeolayoutObjectC() takes 13 positional arguments but 14 were given
