Allow setting position / seeking to a keyframe

[kealist]

It would be helpful to have a function or way to set the player to the nearest keyframe to a position to avoid having artifacts. I see Seek in other libraries that does this, but this only has IsSeekable, but no seek function.

I believe you can set the position with MyPlayer.Position = 0.5 (for example) This would jump to 50% through the media.
