feat: dRICH benchmarks

Add PID reconstruction benchmarks for the dRICH.

• This follows the modularity paradigm by implementing the benchmarks themselves as independent algorithms; they depend only on the input and output collections
• The executable code benchmark.cc opens the input file(s) and runs the benchmark algorithms; it could be generalized to run any such algorithm
