Changelog: https://diffoscope.org/news/diffoscope-244-released/



* Address compatibility with python-libarchive-c version 5.
  (Closes: reproducible-builds/diffoscope#344)
* Testsuite changes:
  - Mark that test_dex::test_javap_14_differences requires procyon.
  - Fix "test skipped" textual reason generation in the case of a required
    version being outside of the required range.
  - Temporarily mark some Android-related as XFAIL due to Debian bugs
    #1040941 and #1040916.
