Description

Add features and blocking keys for the telecom phone number and email values

Related Issues

closes #147

Additional Notes

The work in #26 suggested also making SSN a blocking key, however since the ongoing work on id triplets (#133) will redo the implementation of SSN and also make it a blocking key per RFC-001, this work has been intentionally left out of this PR.
