perf(transmuxer): Avoid repeatedly creating empty Uint8Arrays ( #10100 )
...
In `H264.getVideoSamples()` `lastVideoSample.data` is initialized with
an empty `Uint8Array` which is always replaced before the sample is
pushed into the `videoSamples` array, so to avoid creating a new empty
placeholder `Uint8Array` for each sample, the empty `Uint8Array` can be
created once and then use to initialize all `lastVideoSample` objects in
that segment.
`TSParser.parsePES_` had a similar placeholder empty `Uint8Array` issue,
which I was able to resolve by creating the PES object in the return
statement instead of upfront, that way it can be initialized with the
final data, avoiding the placeholder.
While yes empty Uint8Arrays definitely need less memory than larger
ones, it is still better to not create 100+ unnecessary objects in rapid
succession which then need to be cleaned up by the garbage collector
later on.

perf(TS): Eliminate per-PES wrapper array allocations in parse loop ( #9883 )
...
This PR reduces GC pressure during MPEG-TS segment parsing - it replaces
nested PES packet arrays with a flat array plus a PES-start index,
eliminating per-PES inner array allocations and avoiding spread-operator
overhead when concatenating packets - reduces allocations, hence reduces
GC pressure on low-end devices during long livestreams

chore: Fix deprecation messages ( #6289 )

Some deprecation messages were misleading, and claimed that entire
classes like AbrManager were deprected, when in fact, it was a
particular form of AbrManager (without a method) that is deprecated.
This adds method and other details to the deprecation calls where
needed.
We also had a malformed messsage where join('') was called on the pieces
instead of join(' '). This fixes the formatting.
