Add possibility to Ctrl-v a path

Until now it was only possible to drag and drop a path, but now that I'm using Hyprland this is not implemented. This patch allows me to copy and paste a path either as simple text or from a file manager like Nautilus into the app.

Fix video quality

I chose the wrong video quality for the transcoder, this release fixes it.

First release

This is the first release of Recoder. It works stable for me but being it a first release I'm hoping to get it into some users hands to check it out and give me feedback.
