More robust, atomized catalog build

[marc-white]

Resolves #307 .

This PR showcases a cli.build function (the function that executes the command-line catalog-build instruction) that has been:

• Atomized into discrete helper functions, rather than being one monolithic block;
• (Partially) hardened against failures, i.e., the failure of a single experiment to be successfully ingested should not bring down the entire build process.

Creating a draft PR in the first instance to trigger E2E testing.
