Editing ESP SAs breaks NRLP reassembly untill reload

Changing / adding ESP SAs in wireshark's protocol settings seems to break ✨something✨ in the NRLP dissector which then reports `[sequence was not continuous past <first packet>]`. Reloading the plugins with Ctrl+Shift+L fixes the issue.

Idk if this is an easy fix - if not, at least now we have this issue for documentation 🙃
