Post Vivarium E coli example model

[blairlyons]

Use Case

As a user of the Viewer website, I want to see more example trajectories.
As a simularium developer, I want more test data.

Acceptance criteria

files posted with cards on the simularium home page

Details

trajectory is in s3 named vivarium_ecoli.simularium, with plot data in the api directory
image for card
gif for card

Would also be great to reverse the card order on the page, so that newest cards are at the top.
