Retrieve attributes with 16bit uuid if 128bit fails.

Browse Source 
When retrieving attribute handles using the 128bit base version of a 16 bit UUID some devices will
report "not found". This will attempt to convert the UUID to the 16bit version and try again.

* Adds `to16()` method to NimBLEUUID.
