Add a new pulse.zeroramp.gap property that will enable gap detection and fade-in/fade-out on gaps on playback streams. Make a rule to enable this on chrome, which does not do a cork/pause when a stream is paused but sends out silence. With the gap detection enabled, this allows the audioconvert to perform fades to avoid pops and clocks from sudden DC changes at the gaps. Fixes #4745
