Make sure to set the block stream order flag for sane debugging. This bug really needs to get fixed.

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.
