[Enhancement] Playback speed by library

[ambarnes2]

Is your feature request related to a problem? Please describe.

It would be nice that if the player settings could be custom to the library in. For example, when listening to Audiobooks, I like the playback speed at 1.25x and the Chapter Track visible. But, when listening to Podcasts, i prefer the playback speed to be 1x and have the Chapter Track hidden
