SDK / exoplayer

ExoPlayer extractors (backing `MetadataRetriever`) now parse the color format
from the bitstream so using `MetadataRetriever` should be an equivalent but
more lightweight way to verify the color info.

Also remove try/catch blocks in test code calling into these methods, and add
skipping based on decoder capabilities in the cases where it was missing.
