[API Change] The BGAPIBackend.connect method now takes the same address_type argument as the GATTTool backend [BGAPI].
[API Change] The address_type argument on both backends now requires a value from a new enum, pygatt.BLEAddressType, instead of a string.
Made Python 3 support a priority for both GATTTOOL and BGAPI backends.
Improve reliability of BGAPI backend by re-setting device for each connection.
