Add cards and distribution plots

[mwbernard]

Closes #11

This does a couple things. First off the swarm plots were causing some performance slowdown when crops are switched, so I've taken a stab at a replacement form, similar to some things we've talked about previously. Not 100% polished here, but generally I think showing a vertical distribution of lines conveys the same message as the swarms while being less distracting, and with some tweaks could look really nice. Here are some examples of the plots - I think effectively comparing scenarios, while also giving a good impression of how a crop compares to other crops (the y scale is consistent across all crops to aid this comparison):

sesame:

tomato:

maize:

I also included a first pass at a reusable card wrapper component that wraps around ^ these plots, and also around the crop cards in this view:

@mwbernard i just finished these designs https://github.com/earthrise-media/vacs-map/issues/26 — do you want to include the crop card maps in this PR? i'm happy to wait a little so you have time to generate the static versions to add here

[mwbernard]

@kelsey-taylor hmm I think we can do that in a separate pr, I'm working on a script to generate the svg map images now

[mwbernard]

@kelsey-taylor good call! yeah need to make margins and line width smarter to account for this, gonna hold off merging for the moment.

@kelsey-taylor now these don't get screwed up at small window heights
