Find a third party service for hosting the streamlit app and making it way faster to use

[jbloomAus]

I currently host a public version of the interpretability app with the streamlit community, which is very slow.

I would be willing to pay for a service to host the app, but I need to know that deployment will be very easy.

Checklist:

• [ ] find a third party app hosting service
• [ ] show that it is easy to deploy the streamlit app to this service (https://github.com/jbloomAus/DecisionTransformerInterpretability/blob/c84edb381c53b3f9ef2fa9517e34914a52e15fbd/app.py)
• [ ] show that the service is faster that streamlit community deployment
• [ ] make a PR with a github action which deploys the app
