Create Prefect flow to yank latest CUSP release from GH

[charparr]

We want to keep the CUSP ARDAC data item in sync with the latest data release from the CUSP repo on Github.

For example, when CUSP gets a release 1.2 for example, we want to be able to pick that new data up as rapidly as possible.

This doesn't even need to be a regularly scheduled flow...though it could fire once a month or whatever and do a version comp

Step 1: check Github release version
Step 2: check the version of the data that exists on GeoServer

if github_version == gs_version
-- do nothing

if github verison > gs_ version:
-- download latest CUSP release CSV
-- Download letest CUSP bib
-- execute GS preprocessing script (can this be prefect native?)
-- swap in new file on GeoServer
-- run integration test (ARDAC map item)
-- run integration test (uncached API)

Flow should automatically send email ping for success / failure

Questions:
should the preprocessing script be native to the prefect repo? I think so....
