Implemented a universal encoder based on FFMpeg. I'll get it to work with gif too.
Adding other formats should be easy. In fact, recordingformats can be made into something much shorter. Soon™️
Added a functionality of uploading byte arrays and even files. Created RecordingFormat, which allows me to create states, I guess??, for RecordingContex's. Needed for, eg. gifs, which are horrible and I strongly suggest against, which will actually be stored as files per frame which are QImages encoded with QImage::Format_RGB888 (confirmation needed).
