    Adjust MySQL key lengths to 191 characters
    
    - since default encoding is utf8mb4:
        ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci
    - the max index prefix length is 767 bytes
    - utf8mb4 max character length is 4 bytes, so 4*191 = 764
    - per: https://stackoverflow.com/a/31474509
