Build regularly-updating reports displaying weekly forecasts and/or analysis

Goal: a system that can produce decent default forecasts and then use those forecasts to build reports.

[Notes from 2024-09-01](https://docs.google.com/document/d/15e5Fw4z3qFTntZKg3ModLCHV-z2-bWZec1zIr8rWjZ0/edit):

- MVP: make our current production pipeline publicly useable
- Choose which (best) forecaster to feature
- Bonus after MVP
- make notebooks pretty/more interactive
- rewrite with epipredict
- rewrite with targets
- Is the generation of forecasts a part of this task? Dan points out the language doesn’t reflect that exactly. Logan thinks otherwise.
- Side-note: our partners (CDPH) currently want a good forecaster. This task could provide that to them.
- Modular components (can tackle these one by one):
- Forecast generator using forecast that we think will do fairly well on other people’s data
- Produce report from generated forecasts (in standard format, esp Hubverse format)
- Compatibility with STLT computation style/resources – has to be something that they can run (access to packages, easy to set up, runnable in GH actions?, upload to a website?, etc)
- Outsource the forecast visualization to Reich lab’s [new Zoltar data viewer](https://zoltardata.com/project/360/viz)?
- Hubvis? Not sure if in usable state right now
