Add support for Lyricist

[certuna]

Once #211 is done: Navidrome should import the Lyricist tag (id3: TEXT, Vorbis: LYRICIST). It should be used when:

• Showing it in song details
• Indexing it for searching songs
• Showing songs under the Artist view, under a header (ie, Bob Dylan artist view has a list of his material under different headers: "albums" where he is the Album Artist, "compilation tracks" V/A compilation songs with him in the Artist field, and "lyricist" with songs with him in the Lyricist field)
• Maybe a sub-section of Artists in the left-side menu column
• Maybe provide an extra folder level in Subsonic API when browsing by folder

Note: the Lyricist field can have multiple values
