Add the ability to pick between 3 quantization profiles.
The profile is chosen based on the entropy context at the
block level.

This experiment implements non-uniform quantization where
the width of the bins increases gradually to more closely
match a laplacian distribution of the coeficcients.
Performance Gain:
derflr: 0.15%
hevcmr: 0.675%

NEW_QUANT allows bin widths to be modified as a factor of the nominal
quantization step size. This adds functions to get dequantization
values based on the dequantization offset and 3 knots for a single
quantization profile.
