Updated spatialImp default to be cpp

Updated spatialImp default to be cpp. Updated hotgym anomaly parameters - they need to be a bit different with the new spatial pooler implementations. Updated hotgym_anomaly script to output a CSV file with all the results.
Fixed test failures.

Fixed SPRegion so it internally creates default constructor parameters based on old FDCRSpatial implementation. This is needed for backward compatibility.

CLARegion still uses old spatial pooler. This region is not compatible with the new spatial poolers and really is not being used in the OPF or anywhere meaningful. We should get rid of it.

Updated hotgym and expGenerator description files to use parameter names from the new spatial pooler.

Some old description files in opf/experiments that being used only in tests now explicitly use the old spatial pooler.
