test-copies: test that copies' sidedata can get computed during push
If the source of the push does not have the necessary sidedata but the server
needs them, the client should compute them on the fly while pushing.

This directory is meant to cache artifacts useful for tests (such as bundle).
Those artifacts need to be cached because they are slow to regenerate on each
test but too large to be tracked within the repository. They are not expected
to change between each run and can be cached.
The `./scripts/` contains code to generate the artifact while the `cache`
directory contains resulting artifact.
