feat: add marimo app

[steven-murray]

Adds a little marimo app. With the app you can choose a built-in profile and look at a few sensitivity plots from the profile. We could work on this a bit in a few ways:

1. Add ability to upload your own antpos file.
2. Neaten up the plots a bit so you can see everything at once
3. Host it somewhere

To run the app:

pip install marimo
marimo edit app/sense.py

playing around a little, this is really cool. agreed though with your proposal that this could probably be done after JOSS

[steven-murray]

As a counterpoint -- if this is easy enough to get going in the next day or so, it could be a neat little hook for the paper ("come and try out the app with your favorite 'scope at this link!")

that is a great point! unfortunately I don't think I personally have time to try to work on it within the week.
