Offer to add a new FrameRateConverter to Hybrid.

[AntS]

Hi Selur! Please add my version of FRC to your Hybrid.
I have long experienced all sorts of options. To get maximum smoothness of video clips. As a result, I came to this simple version. It is simple, but works well. Check it out yourself. Perhaps this is the best there is today.
So add this, please, to your program so that everyone can take advantage of it.
Sorry for my English.

### Frame Rate Converter 2
### Increases the frame rate with interpolation.
##
## YV12/YV24/Y8/YUY2
## Requires: MvTools2 (pinterf)
##
## @ NewNum      - The new framerate numerator (if FrameDouble = false, default = 60)
##
## @ NewDen      - The new framerate denominator (if FrameDouble = false, default = 1)
##
## @ Preset      - The quality preset [FilmForBagScene|FilmStandart|FilmForMaxFlow|VideoMusicClip]. (default=FilmStandart)
##
##                 
##
## Presets
## FilmForBagScene:    To handle individual scenes in the film. Which have very strong artifacts in the FilmForMaxFlow preset.
## FilmStandart:       Parameters with minimal artifacts, but sometimes poor flow.
## FilmForMaxFlow:     Parameters with good flow, but in some scenes there may be strong artifacts.
## VideoMusicClip:     Parameters with good flow, and off the replay of the last frame when changing scenes.
