'MrpProtocol' object has no attribute 'add_listener'

Hi @stigger, I was excited to come across your repo, thanks for sharing!

After pairing on tvOS 15, I get an AttributeError as follows when I try to run ./tvscrobbler.py:

ready!
Traceback (most recent call last):
  File "trakt-for-appletv/./tvscrobbler.py", line 32, in <module>

AttributeError: 'MrpProtocol' object has no attribute 'add_listener'

At first I thought it had to do with tvOS 15 tunneling AirPlay over MRP, but it looks like it's authenticated correctly, and I see you had already added support for tvOS 15.

After actually looking at the error, it really does seem that MrpProtocol found below has no add_listener attribute in pyatv.protocols.mrp.protocol.MrpProtocol:

Am I missing something obvious? I'm not sure if the pyatv dependency requires a more specific version than you listed, but I also haven't found anything including add_listener in their commit history either.

After spending a while on this, I figured the solution might be very simple, but I'm not that familiar with pyatv, so I'd very much appreciate any help. Thanks!

Indeed, looks like pyatv introduced an incompatibility in the version 0.9.7. Please try some older versions, 0.9.1 works fine for me.

Just tried pyatv v0.9.1 and can confirm it works great! I'll add that to my requirements.txt for future reference. Thanks for the help!
