Allow Video Playback via External Application

[Quist0n]

What do you want

Add support for using an external video player such as mpv or vlc and such, to handle the playback of videos.

Why

Overall, it would expand the realms of what Cordless can do, and bring it closer to the functionality that the official Discord client
has baked in without sacrificing the terminal-oriented goal of the project as well as keeping the performance benefits of not running a traditional window-ed GUI.

Implementation hints

I have tested and found that running mpv or vlc on its own against a Discord link to a video will allow it to play the video, so that alone is possible. Therefore I believe that it would be a similar to how images are currently displayed through Cordless using feh (on linux at least, though Windows implementation I believe could work similarly). A simple matter of calling the program on the link and letting it run.

P.S: This is my first actual feature request that I have made so if I have missed out anything I will edit this post as needed. Thank you for your consideration.

Basically a dupe of #317

There should probably be a generic file handler where you can have free mappings with a placeholder or so, such as:

"filehandlers": [
  "flv": "vlc -someparam -file $file -something else"
  "mp3": "somemp3player $file"
]

and downloading would be done beforehand, to ensure that applications which don't support streaming will work. On top of that caching could be done as well, in order to save bandwidth 🤷

Closing in favor of #314 as i assume that will solve the needs :)
