Request:
Add the ability to fastforward a replay video by an incremental amount. Currently you can play out the Replay timeline using `ReplayFastForward` function, but the speed is set as an integer / whole number (1-30). I'm requesting to see if we can speed it up using 1.25 or 1.15.
Regular media / videos added to vMix have the ability to fastforward using a percentage of up to 400%, but Replay does not have that ability.

Why:
With TCGs (Trading Card Games) gaining popularity, it is sometimes beneficial to show a match that happened, but show it a bit sped up.
For example, when doing a show - we would record 2 tables playing the game. I would play out one of the games live, while the second one I would replay after I finish showing the first match. And if I have 30 minutes to next round, but the match on 2nd table is 35 minutes long - it would be beneficial for me to still show the match from 2nd table, but just with a speed increase of 20%.
(It would be great if we had an option to keep the audio when increasing the speed, cause sometimes the chipmunk audio might be a fun addition >.<)
