Persistent storage across `pixlet render` runs

[pepijnve]

I'm working on a little app to pull some activity data from Strava and render it to Tidbyt (see https://github.com/pepijnve/tidbyt/blob/master/strava.star). Strava requires OAuth authentication these days (the older perpetual API tokens no longer work). You typically only want to do the OAuth authorization exchange once and then hold on to the received token for future runs.

I initially thought I was going to be able to use the cache module for this, but that's only an ephemeral in-memory implementation at the moment. Is there a supported means of storing/loading bits of data for use across render runs?

Internally we have a cache implementation that uses a durable Redis store. We also have a separate "config" store for things like OAuth tokens or user preferences. We're doing some work now to bring the latter into Pixlet.
