Fixed Critical Quantize() bug, cue Compression.py bugfix marathon

Decompression.py:
Added quality question to main()
Scrapped DeQuantize() mapping
Began DeQuantize()
Compression.py:
Hoh boy.
Quantize() no longer returns an 8x8 array of 8x8 matrices, discarding
ALL of the other values
Confirmed Calc_DCT(Calc_DCT(data)) != data (as feared)

Looks like Decompression.py will be taking a backseat for a bit.
Boss battle.
