Automation of update of FIDO signature site

[carlwilson]

Since v1.6 FIDO can update a pre-compiled updated PRONOM signature file from this web service: https://fidosigs.openpreservation.org/, see code for details. The web service is a container instance of this Docker image: https://hub.docker.com/repository/docker/openpreserve/fidosigs/general. What's needed is enough GitHub Actions magic to:

• Detect that a new PRONOM sig file is available, a manual workflow_dispatch trigger is fine to start with.
• Download and compile the new signature file.
• Build and test the docker container, possibly using the GitHub container registry, see here for similar:
  1. Push and image to the GH container reg for testing: https://github.com/veraPDF/veraPDF-rest/blob/integration/.github/workflows/test-dkr-build.yml
  2. Pull and test the image in another WF: https://github.com/veraPDF/veraPDF-rest/blob/integration/.github/workflows/test-dkr-image.yml
• If tests pass the push the updated container to DockerHub, e.g. https://github.com/veraPDF/veraPDF-rest/blob/integration/.github/workflows/push-dockerhub.yml

The official site should auto-update from here.

This issue was created for the Hackathon 2023 review. @sromkey @darrendignam might be of interest?

I think a docker container that checks and waits for PRONOM changes then compiles the new PRONOM database and presents them in the API would be a batter approach and fully autonomous.
