romanization for lyrics

[haewonskibidi]

add a romanization for japan and korea lyric. or maybe add a translation feature

Thanks for the idea! I opened a PR for the Korean part: #312

What it does:

• Shows a romanized line under each hangul line (e.g. 생각나 → saenggangna).
• Off by default. Turn it on in Settings → Playback, or with a new button on the lyrics island (the button only shows when the song has hangul).
• Mixed Korean/English lines work: English words are left as they are.

Not included yet:

• Japanese and Chinese. I'd like to do them as follow-up PRs. Japanese is the harder one because kanji need a dictionary (around 17 MB) to get the readings right, so it would have to be bundled and loaded lazily.
• Translation. That is a different problem: it needs an external service, and lyrics would leave the device, so I'd leave that decision to the maintainers.

Feedback on the look or behavior is welcome on the PR.
