AudioStream: remove unused youtube-specific fields 

These fields were added in
https://github.com/TeamNewPipe/NewPipeExtractor/pull/810 in
preparation for a DASH support that never materialized … well it did
materialize, but did not use any of these variables.

Since they are youtube-specific, it does not make much sense to export
them in the generic API, lest people start depending on them as if
they belonged to all backends.

Well, 4 variables are actually already depended on in places, they
will have to be checked separately. But this is the low-hanging fruit.
