Zsolt Matyas fff602358f CEA608: Limiting duplicated command checks to immediate frames 
Reported in https://github.com/google/ExoPlayer/issues/3860
For failing examples see the github link above.

[Problem]
We drop matching control codes even if they are not received on
consecutive frames.

The specification says
"(4) If the first transmission of a control code pair passes parity,
it is acted upon within one video frame. If the NEXT frame contains
a perfect repeat of the same pair, the redundant code is ignored."

Keyword is the NEXT. The frames must arrive immediately after
each other.

See https://www.law.cornell.edu/cfr/text/47/79.101

[Solution]
Set an additional flag when any data is processed. Control code
duplication checks should be limited only for the first control
byte pairs processed after any control code.

[Test]
Sarnoff tests have equivalent CEA708 and CEA608 Streams.
