SonyBridge: reconstructing second-generation Sony headset control

SonyBridge extends a desktop Sony headset client to handle a second generation of its Bluetooth RFCOMM control protocol. It documents frame boundaries, service UUID families, the v2 initialization handshake, host acknowledgments, and commands for battery, equalizer, and DSEE data. The app offers controls on macOS, Windows, and Linux.
