Allow SlimBrowse to support duration

SlimBrowse currently does not seem to support duration values passed by plugins to Material skin. This, together with a trial trivial change to LMS (LMS-Community/slimserver#1348) allows Material to display track duration and total duration. Works with lms-plugin-tidal and Spotty-Plugin.
