Add support for PSNR calculation based on stream bit-depth

This patch adds support to compute PSNR based on stream bit-depth when input bit-depth is lower than stream bit-depth.

Based on a similar change for AV1 (libaom): https://aomedia-review.googlesource.com/c/aom/+/116721

However, unlike AV1, we change the default to use stream bitdepth.

STATS_CHANGED possibly for rare cases.

For issue #344
