Checklist:

• I have ran Ruff against my changes (via poetry: poetry run python -m ruff check . --preview, use --fix to automatically fix what it can)

• New and existing e2e tests pass locally with my changes
• If reliant on changes of third party dependencies, such as Impacket, dploot, lsassy, etc, I have linked the relevant PRs in those projects

• I have made corresponding changes to the documentation (PR here: https://github.com/Pennyw0rth/NetExec-Wiki)
