Rife-App 1.7.2

Lots of change, hoping it don't have a lot for new bugs as well.

• New options to interpolate X16 and X32, why not?
• Concat option create a new video instead of replacing the default output.
• You can select a PNG image as input, the app will scan the PNG folder for all PNG files and order them by name. I'm sure this workflow can be improved in the future.
• You can export PNG sequence, the mp4 is still created with this option enable.
• [1.] You can select the CRF to change the quality of the output MP4
• [2.] There is a few models to select, they change the output result. Personally I think that 2.3.1 work pretty good for most animations, but you have to test each model to see what work best for your input. Previous version of Rife-App use the model 2.4
• [3.] To help test the output, you can select to just render a few frames of your input.

[4.] This is a experimental option, here a example, an animation using this 3 frames with 32X:

Doing a regular interpolation X32, this is the result:

And here the result with "Smooth Interpolation"

The idea is to give a little more energy to animations with few frames, like gifs.
