Please add those Lyrics other sites

[Atanacius]

Well, this extension isn't perfect ONLY due to the fact that the source of lyrics sites are really too less than expected.

Anyway, this is a solid extension, I cannot say it's bad, but, yeah, not perfect sadly.

So, in the process to improve the lyrics finding process, you can also add those marvelous sites:

• https://www.lyricsdb.co
• https://www.musixmatch.com

(for the moment).

Please add those. I tryied to look at your LUA code, but.. I'm really not a LUA programmer yet.
