- Packaging fixes

-----

- Kafka output improvements
- Moved some key values (`report_id`, `org_email`, `org_name`) higher in the JSON structure
- Recreated the `date_range` values from the ES client for easier parsing.
- Started sending individual record slices. Kafka default message size is 1 MB, some aggregate reports were exceeding this. Now it appends meta-data and sends record by record.

- Fix decoding of attachments inside forensic samples
- Add CLI option `--imap-skip-certificate-verification`
- Add optional `ssl_context` argument for `get_dmarc_reports_from_inbox()`
and `watch_inbox()`
- Debug logging improvements

- When checking an inbox, always recheck for messages when processing is
complete
