This can happen if the quality is changed from an avmerge source
to an integrated source, and then changed back to an avmerge source
Close is called the first change, but on the last change, it's
called again because the avMerge object is still present, resulting
in InvalidStateError

If a fetchRange network request finished after the quality was
changed, there would be a "InvalidStateError: An attempt was made
to use an object that is not, or is no longer, usable" because
appendSegment was trying to append to the sourceBuffer that was
unusable after the video src was changed to a new mediaSource.
Adds a close method to the AVMerge class to properly clean and
close everything so these sorts of errors won't happen.

from #15:
"[..] Firefox's VTT parsing [ignores] newlines. So if the cue starts
with a newline, that cue will have blank text (a corollary is that
the first sentence uttered will fail to display in the automatic
captions [..])."
