It may happen that if we have simulcast track with, let's say, 2 streams
A and B, we can receive frame X on A and then receive it again on B
when there is a switch from A to B. TO correctly handle it we need to
skip second receive of X. Later we need to add metric which will show
how many frames were in between when X was received twice.
