- Apply multiple enhancements to `clean-processed-folder.py` so that it runs fast
enough to keep up with the generation of log files in pipeline capture mode. These
changes increased the file processing rate by a factor of 100.
- Preprocess the filebeat registry into a format for checking file presence using the
`in` operator.
- Replace regular expression pattern matching for mime file types with list searching.
- Refactor running `fuser` with the subprocess module for increased speed.
- Treat zero-length files, which have no mime type, as eligible log files.
- Update logging to improve the ability to monitor script performance.
- Fix the search for Suricata log files which was excluding log files created in the
pipeline mode.
- Run `clean-processed-folder.py` every minute in order to minimize the risk of
overflowing the partition where the log files are stored especially in the pipeline
capture mode.

Integrates Manufacturing Message Specification (MMS) protocol analysis into Malcolm. MMS is the underlying protocol for TASE.2/ICCP, which is widely used in energy sector control systems for inter-control-center communications. Protocol parsing is handled by Zeek plugins from the DINA community project.
Changes include:
Testing:
Verified against captured MMS/TASE.2 network traffic replayed from pcap files.
