Handle read not permitted when subscribing

[luigi311]

For some reason in my library when connecting to my Avanti smart trainer i can issue a connect and then when it tries to subscribe for notifications it raises a Read not permitted error. This doesnt seem to cause any actual issues as ive been masking that error in my fork but figured i would open a ticket to discuss it here.

Bleak 3 added in a BleakGATTProtocolError exception which broke my mask so it reminded me to come and raise the issue here to discuss what a proper way to handle this would be, as of right now im just masking it with the new error system now.

Also with this it might be worth bumping up bleak officially in the library at some point.

after 3.0.0: luigi311@b721740
