Series bass: Rework Scan Delegator | expand

Commit Message

Iulia Tanasescu Nov. 20, 2024, 10:25 a.m. UTC 
This adds public BAP helpers to convert iso_qos to bap_qos and reversed.
This is needed for the BASS plugin to handle the Scan Delegator (BASS
Server) role internally (to create/handle BAP streams when receiving the
Add Source command from a Broadcast Assistant).
