* WIP commit
* WIP commit
* Remove debug
* Revert to reduce diff
* Fix tests
* Determine spatial layer from track info quality if non-simulcast
* Adjust for invalid layer on no rid, previously that function was returning 0 for no rid case
* Fall back to top level width/height if there are no layers
* Use duration from RTPDeltaInfo
* Use rtcscore-go to calculate audio/video score

* Move SpatialLayerForQuality to utils/helpers
method is required in rtc,sfu and connectionstats pkg
Moved to utils/helpers.go to remove cyclic deps

* Improve frequency of stats update
Prometheus stats are updated as the data becomes available, instead of
aggregated along with telemetry batches. Node availability decisions can
now react much faster to these stats.
* use the same intervals for connection quality updates
* Use delta stats throughout and avoid calculating deltas in telemetry
* Fix a few things after testing
* Remove debug
* Fix tests
* delete instead of setting to nil
* Point to the latest protocol
* Add a resync API to sfu.DownTrack
Also passing in logger with context into sfu package. More to do here
with proper logging context in all modules, but this is a start
* Remove debug code
* fix tests
* audio connection quality mos for publisher stats

score is calc at 5sec interval. Client fetches score before first
score is computed
