Tool for gzipping a workspace on backend

[bloodearnest]

We have various large workspace with many uncompressed csv files

We want users to switch to csv.gz, but we don't want them to have to re-run all the jobs because a) time and b) it wouldn't actually remove the existing files

Instead, we should write a new jobrunner.cli tool that, for a given workspace

for each .csv in the workspace:

• gzips the file
• updates the database for any actions that produced that file to point to the .gz version instead.

This would then allow the user to switch to csf.gz in their project.yaml and code, and everything should just continue as it had been that way all along

Bristol are going to create new workspaces that use compressed files, and archive the older workspaces, so we can then compress and archive them.

So this tool might not be needed
