Twitch-archiver

**IMPORTANT NOTICE**
Any stream archived without a paired VOD grabbed with the `watch` flag enabled is likely corrupt due to an overlooked error with the previous archiving method, this archiving method was and still is not guaranteed to be flawless, but is a "best effort" attempt at archiving these kinds of streams. Apologies that this wasn't caught sooner.

**Changes and Fixes:**
* Rewrote object for storing stream segments to prevent parts being potentially overwritten.
* Add flag for ignoring part corruptions used for streams without paired VODs.
* Fix stream merged with ffmpeg being out of order if stream was buffered before archiver ran (36).
* Fix streams without a VOD starting from a non-zero part number if buffered.
* Fix streams without a VOD not being downloaded if they have unusual part durations.
* Fix buffer being overwritten if archiving restarted during buffer interval.
* Add debug flag to grab stream and ignore any paired VOD.

**Changes and Fixes:**
* Fix regression on Windows when merging VODs (34).
* Fix error if no channel videos available in live-only mode.
