Add support for Chimera 40-202's chimera_throttle_framerate

[BinToss]

Throttled framerate + no V-Sync is preferable for monitors that support Adaptive Sync.
It's also a good alternative to Halo's terrible V-Sync implementation until we can control GPU driver settings.

If VSync is off, set the framerate throttle to the Vsync value - 1.
The value is stored in chimera.bin

My chimera.bin is located at J:\chimera.bin for some reason.

Offset 0x2f is used to determine if the fps value is float or int.
A value of 0x40 indicates integer fps throttle.
0x3f indicates a float.
