Silan cue-in/out analysis now moved to airtime_analyzer * Added a new CuePointAnalyzer using silan (will remove silan stuff from pypo later) * Makes silan analysis slightly more reliable for certain short files. * Fixes CC-5961: Audio duration cutoff for WAVE files * Added unit tests for the new analyzer and improved code coverage slightly * Added unit tests for WAVE metadata extraction and an invalid WMA file
