Added support for Tidal lyrics and fixed parsing error when preferred quality too high

[M4TH1EU]

Hi,

I though this nice little tool was missing the lyrics part from its competitors so I implemented it. Only very little code was required so it shouldn't cause issues anywhere else in the code.

I also fixed a JSON parsing error that happened when the preferred quality for a media wasn't available and would crash the app (simple retry with quality - 1)
