Investigate: Android 12, BLUETOOTH_CONNECT & getBondedDevices()

[dariuszseweryn]

As hinted in #768 — on Android 12 there apparently is a need to have BLUETOOTH_CONNECT permission when calling RxBleClient.getBondedDevices().

If you, the reader, have an Android 12 device and you're willing to help and check — please do.

If that is the case update Javadocs.

Hi Darius, I made the original PR that I can see you've merged now, and that seems to be entirely correct based on what we can see of usage.

How should we go about it from here?

[dariuszseweryn]

@DaBs I am thinking whether there should be a separate library exception or is the system one just fine, especially that this API is synchronous

[DaBs]

@dariuszseweryn I think system error should be fine honestly - getting the error is clear and concise. I also don't remember seeing us map other instances of permission errors, but maybe I'm wrong?

I have added that info to Javadoc and left the feature as it is. Thanks for the opinion!
