Support for high precision framebuffers and dither noise (RT64) (#252)

Browse Source 
* 64 bit framebuffer for rt64

* Remove mention of motion blur cap from readme

* Add graphics.json option to control high precision framebuffers, disable clamping alpha for accumulation blur when using high precision FBs

* Increase dither noise strength at higher resolutions to make it more noticeable
