Add constraint release versioning and mutation rate table path functions

- Introduced CURRENT_CONSTRAINT_RELEASE variable set to "4.1.1".
- Updated CONSTRAINT_RELEASES list to include "4.1" and "4.1.1".
- Added _public_constraint_mutation_rate_ht_path function to retrieve mutation rate table paths.
- Modified constraint and constraint_mutation_rate functions to utilize the new constraint release versioning.
