Since ive added some new settings into settings.json and ppsettings.json, osr2mp4-app also had to be updated.

Preview (Video):

The big ones

  * Background video (no smooth fadein fadeout on in_break for now)
  * Background blur (for background image)
  * Customizable URCounter
  * Resampling (resampling code is really sus)
  * Moved strainsettings.json into ppsetings.json so it can be edited with osr2mp4-app's CustomPP

The small ones

i forgor :skull: but nothing major im sure of it
