RNTuple as mapping #692

The LHCB analysis example loads an RNTuple into a LLAMA view via a manually written loop, copying field by field. Alternatively, we could define a LLAMA mapping exposing the RNTuple to LLAMA directly and then use LLAMA's layout aware copy routine to transfer the data to a destination mapping.
