Add 2BPP helper functions for our blocks.
...
Namely, there are two things that we need to do:
1. Figure out the sub-mode based on the mode bit and the structure of the modulation data. The comments in Block.h describe how we do this.
2. For a given texel index, return 2BPP texel modulation bits.

When going from 344(3/4) pixels to 4555, the alpha channel only has a zero appended to it. Hence we must clear that bit for each pixel that was transparent during decoding.

Fix Bilinear upscale
...
There were a couple of fixes.
1. Add another set of pixels to an image that represent the fractional bits that get populated as a result of doing a bilerp.
2. Do not consider individual axes when doing the bilerp. Instead, assign a weight to each of the different texels that we will use for the bilerp. Then, combine them and save the fractional bits.

...
1. Make sure to use the same lerping code for both modulation modes when decompressing.
2. Accept a flag during decompression that outputs the debug images that were computed during decompression.
