VIDEO_ANALYZER works on all resolutions!
TMDS_(CHANNEL_)DECODER: Rolled back to the previous commit and extended by DVI support, which also seems to work. The stateless channel decoder didn't work because there are collisions of TERC4 and pixel 10 bit vectors.
Now I just added transitions to skip the guard bands not present in DVI mode. During video period, no TERC4 data is interpreted.
I also refactored TMDS_DECODER, converted functions to conditional signal assignments.
