Add support for embedding both synced and unsynced lyrics

[nechtarg]

Requested Feature

As of right now using synced lyrics like this:

spotdl --lyrcis synced genius --generate-lrc

will result in only the synced lyrics getting embedded into the resulting file. This results in an inferior output, as clients not expecting synced lyrics will output them not formatted (that is with the timestamps and without section headers like [Chorus]).

Possible implementation

Add an option to embed both the synced and the unsynced lyrics, not forcing the user to choose between them.

I am not sure if that's possible. MP3 and WAV tag specification allows the use of both synced and unsynced but I am not sure about the others. Right now like you said synced lyrics are saved in both synced and unsynced files. I will fix this and convert the synced to unsynced.
