mime-types 3.1

*   3 bug fixes

    *   A test for MIME::Types::Cache fails under Ruby 2.3 because of frozen
        strings #118. This has been fixed.

    *   The JSON data has been incorrectly encoded since the release of
        mime-types 3 on the +xrefs+ field, because of the switch to using a Set
        to store cross-reference information. This has been fixed.

    *   A tentative fix for #117 has been applied, removing the only circular
        require dependencies that exist (and for which there was code to
        prevent, but the current fix is simpler). I have no way to verify this
        fix and depending on how things are loaded by `delayed_job`, this fix
        may not be sufficient.

*   1 governance change

    *   Updated to Contributor Covenant 1.4.
