bug(h264/h265): DTS may stay the same (#119)

Foe some reason in the code the monotonical increasing did forbid having the same value as before, while purely mathematical definition of a "monotonical increasing" does allow to have the same value. Fixing it. ITS: bluenviron/mediamtx#1002 Signed-off-by: Dmitrii Okunev <xaionaro@dx.center>
