pgssubdec: fix incorrect colors.

Browse Source 
On Blu-ray colors are stored in the order YCrCb (and not YCbCr) as mentioned in the specifications:
see System Description Blu-ray Disc Read-Only Format, 9.14.4.2.2.1 Palette Definition Segment

When decoding a Blu-ray subtitle, the colors were incorrectly set.
