Paul … as per my email (figured out I did have a login after all!)
Not sure if it’s relevant or not, but I stumbled upon this repo recently.
It seems Christina Harlow (https://github.com/cmh2166) has done a lot of work in this space … so it might be worth piggy-backing on her efforts or at least making contact for her input.
Looking under her repo, there appear to be several recently maintained python-based tools …
Rgds.
