Rewrite tooling in `geodude`

[Alex Naka]

Tracking issue for a rewrite/reboot of stuff in genpen in its new home, geodude.

Some things I want to be thinking about during this:

• #5
• #6
• Find a better flow for quickly exploring parameter space and storing many configs and outputs
  • possibly leaning into vsketch more is the answer here for visualization
  • configs are harder; hydra might be worth thinking about
• keeping notebooks cleaner
