feat(users/Profpatsch/lyric/ext): add lrc upload & ms offset

This adds support for uploading the lyrics part of an .lrc file to
lrclib, see https://lrclib.net/docs

I pretty much only used ChatGPT to translate the rust “proof of work”
challenge to nodejs and it worked first try lol.

Before uploading the lyrics, I construct a webview with a preview of
what is going to be uploaded, and then only upload when that is
accepted. Pretty sweet.

Also adds two commands for increasing/decreasing the current timestamp
by 100ms and starting playback from 2 seconds before that, very handy
for fine-tuning lines.
