As noted in issue #72, pypng was missing from the list of pip packages installed for the Docker image, which is required for dish_obstruction_map.
Without extraneous changes this time....
They're still pinned to specific versions, just the newest ones as of right now. This should avoid the need for the ARM64 build to compile any wheels that need native code.
Also, reorder how the pip packages are listed for easier maintenance.
Add the Python packages required for the InfluxDB 2.x client to Dockerfile, at the specific versions that I tested with. Most of the package dependencies overlap with the InfluxDB 1.x client package, so there was not much added.
Note the new script name in the relevant parts of the README.
This should have gone in with change c35588d01f, but I forgot that the Docker config has a separate list of package versions so they can be pinned to specific version numbers, instead of just specifying a minimum.
Remove grpcurl and grpcio-tools from container configuration and add yagrc, so that the direct reflection support in the Python scripts can be used. Also, pin all Python packages, including package dependencies, to specific version numbers, since that was already the case by happenstance due to the way Docker caches its build images and an undesirable version of the protobuf package was being cached.
Addresses #23, which was directly about this change.
Expected to also address #22, as a result of pinning the protobuf package version.
Should also prevent a recurrence of #18, since yagrc will automatically get any new dependant protocol files via reflection.
For now, the default docker command includes the altert detail but not the obstruction detail, because that's what the old dishStatusInflux.py script had.
