Add fuzz testing to CI

[andygrove]

What is the problem the feature request solves?

I would like to have some version of the fuzz testing tool running in CI.

Initial thoughts on tasks:

• Implement unit test that runs fuzz testing if an env var COMET_FUZZ_TEST is set
• Add GitHub action/workflow
• Add mechanism so that we can skip known issues (either fall back to Spark or skip certain tests)
