Multiple delimiters for splitting artist field

[dakrk]

Currently, the artists fields are only split by , . This is unsuitable for files using Vorbis comments with multiple Artist tags, as mpv will concatenate them together using a semicolon as a delimiter, like so: Artist 1;Artist 2;Artist 3.
Some MP3s may also use a slash as a delimiter, like so: Artist 1/Artist 2.
As mpv-mpris only handles a comma with a trailing space as a delimiter, none of these are split and programs using MPRIS could treat this as one huge artist field.
Unfortunately from the looks of things, libmpv doesn't provide a method of returning this as an array, and there's the possibility that some artist fields will have multiple sequences (possible situation: Tyler, The Creator;Artist 2) which will make this even more of a pain.
Perhaps different file types could have a delimiter priority.
