Add compression test

[kion-dgl]

It looks like we will need to compress Megaman's texture in order for it to be put back into the game. The scope of this ticket is to add a test for compression to see if we can take a texture, decompress it, compress it and then see if it works with decompression again.

In terms of things to do first there's a sanity check for decompressing and decoding that game's existing textures.

We need to do this three times for PL00T.BIN. this will be for the body texture body texture with alternate palette, and face texture.

Once we confirmed that decompression works, then we'll need another test to compress the texture and then see if it can decompress with the same algorithm.
