ae878d4aed Split BPTC decompression into two stages. 
In one stage, decompose the block into logical bit values. Then,
if we want to decomrpss into an output image, do the proper interpolation.
Otherwise, return the logical block as-is to do things like figure out proper
mode crap and other stats.

fb7805d875 Bring CMake integration up to date. 
- Add a way to generate a FasTCConfig.cmake file so that you can
use cmake without having to install it.
- Add install paths for users that want to install it.
- Hide all public headers in FasTC/ qualified include path, this way we
know what files are public directly from the source. Also, it lets us
define build-tree and install-tree include directories a lot easier.

19b5d478a0 Fix small bug: 
Set the bits that aren't being used in the texel data to zero so that
the integer decoding sequence recreates the proper texel values for
trits and quints that don't have as many bits as there are expected
values.

ff1181e12a Lots of QOL fixes: 
1. Avoid the need for multiple-of-four input textures. If you don't pass
a multiple of four then we'll do our best to pad the image.

2. Fix a bunch of bugs where we didn't accurately report why we couldn't
compress a texture and just crashed instead.

3. Some code refactoring to make certain if statements more readable.
