Package as Web App along with official Docker builds

Hey :)

Firstly I want to applaud you for showing this much love for LRC and lyrics in general! I think it's also thanks to you, so many media players have picked up LRC support in recent times.

My request would be - since the app is built using web technology anyhow - to offer a web app native solution. I bet I'm not the only one managing their music collection centralized on their NAS but accessing it from different machines, all of which run widely different operating systems.

It'd be great to have equal access to the UI on any of those and to run the app headless in the background.
