Cleaned up the u32 trifloat implementation.
...
This also makes encoding faster. However, it no longer does
rounding to the nearest precision when encoding, and insead does
flooring. This seems like a reasonable tradeoff: if you want more
precision... you should use a format with more precision.

Removed the experimental luma-chroma color format.
...
It was a worthwhile experiment, but for it to really work it needs
a really proper luma-chroma separation, which is both slower than
I really want, and requires knowing the colorspace being used.
I might make another go at this based on the TIFF LogLUV color
format, requiring XYZ as input.

Use a better chroma formula for the RGB32 format.
...
This makes much better use of the bit space.

More work on the packed HDR RGB 32-bit format.
...
Switched to a different chroma encoding, which is notably faster
and never produces negative values when decoded.

Implemented a "tri-float" encoding, similar to RGBE.
...
This implementation trades less range for more precision, giving
9 bits to each mantissa instead of just 8 bits as in RGBE.
