Seeing some panic due to sender view being nil. It is possible to have
nil sender view and not-nil receiver view. For analytics, only sender
view is used. Handle nil properly.
Receiver view is used for connection quality.
Sender view is used for analytics. One thing that this introduces is
that sender view uses the packet loss information from receiver view as
true loss is available only in the RTCP Receiver Reports received from
the remote side. So, the time alignment is off, i. e. receiver report
happens periodically and it includes information till the time at which
it was sent from remote side, but sender could have sent more packets
after that time.
The split should ensure that analytics does not rely on remote side
sending proper receiver repoerts albeit at slight misalignment of loss
statistic for remotes that send RTCP RR (which should be majority of the
cases)
Actually, was caused by down track not initialising mime, but it is good
to ignore unknown mime.
Also, added ulpfec sa SDP has that and there was a conversion which was
returning unknown. Also, note that the mime types use audio for RED and
video for flexfec and ulpfec although they are not media type dependent.
Maybe, at point need to introduce `MimeTypeAudioRED` and
`MimeTypeVideoRED`.
* Normalize mime type and add utilities.
An attempt to normalize mime type and avoid string compares remembering
to do case insensitive search.
Not the best solution. Open to ideas. But, define our own mime types
(just in case Pion changes things and Pion also does not have red mime
type defined which should be easy to add though) and tried to use it everywhere.
But, as we get a bunch of callbacks and info from Pion, needed conversion in
more places than I anticipated. And also makes it necessary to carry
that cognitive load of what comes from Pion and needing to process it
properly.

While working on a different service, noticed delegation of setting up
routes to the service itself. So, making that change and making some
methods internal only as there is no need to export them outside the
service.
* Do not skip due to large RR interval.
With sequence number adjustment, it will report some packets missing
which is fine.
* do not seed if already initialized
No functional change, just logging reason was confusing.
Also, log no packets case. Seeing some instances in staging where there
are periods of no packets received. Trying to understand better.
initially.
Out-of-order reception is detected and dropped before this change. By
moving the adjustment to that point, potentially more reports can be
processed.
TrackSubscribed is meant to give publishers an indication when the subscriber
is ready to receive its audio. When there are hidden recorders in the room,
we do not want them to trigger this event.
My previous PR was trying to fix a premature transition from CONGESTED -> NONE state.
But, that introduced a bug which accelerated the transition from EARLY_WARNING -> CONGESTED state due to holding the `queuingRegion` state variable.
Fix by not holding `queuingRegion` in state and take result of
processing runs.
NOTE: This can still use some work to make the state machine cleaner.
Initially, I was passing around a bunch of variables which was uncouth.
Then moved things to state which made code easier to read and also log
different things, but it causes problems like the ones above. Will take
another look and think more about making it more robust.
* Use nonce in data messages to de-dupe SendData API.
With API retries, it is possible that some data messages are sent
multiple times. Check the nonce (if present) to de-dupe data messages
before forwarding it to the clients.
* add nonce to UserPacket
* defer unlock
* 128-bit UUID as nonce
* - UUID nonce
- make a UserPacketDeduper module for easier re-use.

* Resolve newer participant using higher precision join time.
Also, keep it consistent based on participant SID if everything else is
the same.
* switch to compare semantics
* fix
* Do not seed if stream is already writable.
It is possible that in migration case, when the forwarder state is
fetched from migrating out node and used to seed downtrack, it has
already started due to the time it takes to get the state. Seeding in
that state will reset things and cause large sequence number gaps
potentially.
* do not take lock
