Browse Source 
-Reduces message and event histories per channel from 500 to 200.
-Resolves issue of tuner freezing due to cancelled USB transfer buffers not being resubmitted.
-Reworks the audio playback system to remove in-progress call preemption and remove thread locks which can cause glitchy behavior during audio playback.
-Updates audio outputs to also use single thread pool for processing audio segments.
-Updates MBECallSequenceConverter to batch convert MBE to WAV audio.
-Unifies recording filename prefixes across baseband, mbe and binary recordings.
-Resolves issue with registering heartbeat manager to dispatcher.
-Uses single-thread thread pools for Dispatcher to support batch & process to overcome context switching consistency issue in Windows.
