This example is based on the following TTree/RNTuple benchmark: https://github.com/jblomer/iotools/blob/master/lhcb.cxx

The example reads experimental physics data through RNTuple into a LLAMA view, runs an exemplary analysis, fills a historgram and displays the result.

There is a workaround for generating up-to-date RNTuple's, as described in jblomer/iotools#9 (comment). Let's test that and then merge the example.

The result is now the same as the corresponding analysis from @jblomer's iotools:
