Allow video/audio upload

[JunkiEDM]

What should be added? The ability to upload audio/video (mp4,webm,mkv,etc; mp3,wav,flac,ogg,opus,etc) with the inbuilt uploader used for images, probably as an opt-in toggle since some hosts like imgur dont support it, but others like nuuls and x0.at do.

Why should it be added? It's cumbersome to have to go to the site to upload video/audio files when its the same site you use for image uploading via chatterino/dankerino.

The uploader was never meant to function for video. It loads the ENTIRE file into memory before transferring it now imagine uploading several hundred megabytes of file using that. However I am open to expanding the uploader to audio formats too.
