MoQ fixup list

[RichLogan]

After the plethora of changes to support libquicr directly, and MoQ, there are some relatively minor things outstanding or missing:

• Double free on leave
• Teardown and strong reference cycles
• Timestamps from LOC / object headers (waiting for libquicr support).
• Labels not working (Restore label functionality #472)
• Cloud relay setup / config
• Update testflight groups for external testing. Remove deploy job.
• Rename public facing (Rename to quicr-mac / QuicR #474)
• Remove or fix cleanup timer / task code (Redo cleanup strategy for MoQ changes #476)
• Use profile's priority and TTL values (Pass priority and TTL #477)
• Add correct starting group IDs. (Use time for group IDs like qmedia #478)
• Remove visible error about missing format when joining mid-stream (Don't show error when midstream #479)
• Export client and track sampled metrics, using relay ID received via ServerSetupReceived() (Report libquicr metrics #482)
• Expose ServerSetupReceived() relay id/name into UI. UI should indicate which relay they connected to and if there is an error, it should reference the relay id/name. This will be used to expose which actual relay was used behind anycast and LBs.
• Non macOS platforms have not been tested (Append MinimumOSVersion plist entry #496)
• Re-add or intentionally drop runtime Publication & Subscription editing.
• Correct responses for client events
• Correct responses for publish track handler events
• Correct responses for subscribe track handler events
• On status events, especially resuming publications, make correct decisions about group changes.
• Automate & publish docs
• Scrub configs for minimal set
• Rename dependency script / scrub for QMedia references
• Ensure zero-copy in obj-c layer
• Look at extracting available bandwidth from metrics.
• Encryption / SFrame in client code
• Rename all usages of "Decimus"
