Show HN: A simple Python script for extracting CSVs from FortiGate firewalls

Previously we were using FortiManager to manage a cluster which has CSV export functionality, however for reasons too long to explain on HN, we no longer use FM and simply use FG directly. We occasionally provide policy and DNAT exports to customers and internal teams, so this script replaces what we used to have and allows for a bit of on-the-fly editing too.
