Changing the ETC1S->BC4 and ETC1S->ETC2 EAC transcoders so they convert from the source red channel, not source green. Source red makes more sense when transcoding to BC4/BC5, especially when the source texture only has color slices. BC4 is red, and BC5 is red/green. This change makes no difference if the source texture slices are grayscale.

Adding more checks to canonical Huffman decoder's table initialization function. They don't seem necessary, as I didn't discover them during fuzzing. These fixes are precautionary.

- Fixing minor block artifacts on pure 2 color B&W blocks when transcoding to BC1/BC7. This was caused by the ETC1S blocks using extreme ETC1S settings: codetable 7 (the one with the largest intensity deltas), using blocks with selectors that took up the full range (0-3), but the blocks only actually used the two outlier colors (0 and 3 only). The ETC1S->BC1/BC7 table based format conversion system doesn't realize that only the outlie colors were going to be used (i.e. not all 4 colors, just the outer 2), and so the quality of the transcoded block suffered because pure black could not be mapped. In BC7 mode, we now switch to pure BCT (block truncation coding) for any blocks with <= 2 unique colors, independent of their selectors.
