How to receive AVRCP-commands while being A2DP-source?

[BGKMM]

Hello Phil,

first of all: THANK YOU for your efforts on building this library!

Being new to esp32, I'm trying to use it to send audio from ESP32 to headphones and speakers (i.e. source to sink), which is already possible (due to your great documentation and examples - thanks!).

Now, I would like to receive AVRCP commands (play, pause, next, previous, maybe volume) to control the ESP32 via speakers buttons (like lemonjesus requested in this issue).

Is this possible meanwhile within the library? How can it be achieved? Any hints will be highly appreciated.

Thanks in advance an greetings,
BGKMM
