(toDo) AR sound sync: make "process latest packet only" user-configurable #309
Description
PR #231 has introduced Sound sync "frame dropping" unconditionally. This is not adequate for all networks - for example WiFi delivers small UDP packets in "batches", and only using the newest packet may cause very jaggy effects.
Add AR option "Receiver can drop packets"
- always (current behaviour)
- only when silence detected
- never (old behaviour)
