Add C++ tests (misc directory) for new implementations Faust::hierarchical, Faust::palm4msa and a new test to factorize Hadamard matrix with the 2016 implementation (Faust::HierarchicalFact) in order to compare with the new implementati
on.

- The tests hierarchica2020Hadamard and hierarchicalFactorizationHadamard receive optional argument to define the Hadamard matrix dimension.
- The test palm4msa2020 receives an argument to choose the implementation to run (Faust::palm4msa or Faust::palm4msa2).
