Bump RxAndroidBle to support android 12

[saty9]

The current version of RxAndroidBle (1.7) does not support new android 12 permissions so requires fine location permission unnecessarily. Version 1.13 and above fixes that dariuszseweryn/RxAndroidBle#762.

Apart from the new permission model, we've also experienced stability issues and crashes when building the app with targetSdkVersion = 31. And there's a 1st of August (1st of November) deadline for updating your target version: https://support.google.com/googleplay/android-developer/answer/11926878?hl=en

In these circumstances, we really need a version of this lib that officially supports Android 12. Dear maintainers, please consider updating.

@dariuszseweryn Sorry to pull you in here, but I see all the work you did on https://github.com/dariuszseweryn/RxAndroidBle wrapped by this MultiPlatformBleAdapter, so maybe you have some insights.

To support Android 12 and the new permissions, the MultiPlatformBleAdapter needs to be updated, so the react-native-ble-plx library can be updated as well later.

Do you have any insights about the maintenance of MultiPlatformBleAdapter?
Should we consider the MultiPlatformBleAdapter and react-native-ble-plx projects dead?

Thanks
