How to rollback to an older EOSIO.CDT version with brew

Recently, EOSIO.CDT 1.7 has been released, but it has a [severe bug] where it crashes when trying to compile a contract using an <code>eosio::ecc_public_key in one of its table structures. If you're on MAC you might wonder how to roll-back to a previous EOSIO.CDT version using brew. Sadly, there's no versioning for the EOSIO.CDT releases, but you can still rollback to a previous version by installing it directly from an old GitHub commit.
