2fd14dd8eb avcodec/simple_idct10: improve precision 
omse goes from 0.03060703 (which fails for dct-test) to 0.01663750.
This also actually improve the error of decoding the sample generated
by fate-vsynth3-dnxhd1080i-10bit using simple_idct10 to FAANI, which
goes (when resampled to yuv422p) from:
stddev:    0.06 PSNR: 72.28 MAXDIFF:    1
to identical.

c7e14a279f dnxhddec: use dequantization formula from specs 
The current one, while correct, does not yield the best possible
results. The specificiations suggest another formula, which results
in quality gains in the decoded output from fate tests. This
justifies changing said formula.
