## Summary
- Added a `listen_on_ports` set in the `IOSoftware` class to enable software listening on ports in addition to the main port they're assigned.
- Also added something I missed in the `CHANGELOG.md` from user login ticket 🙃
## Test process
- Tested listening on ports with a dummy listener software class and counted frames snooped on.
- Also tested that the actual software that the posts being snooped in on still works as expected.
