Packaging mode for studies

[dogversioning]

-Adds a new cli param to the build argument, --prepare, which renders queries instead of execute them
-Adds a fixture to replace individual instances of clearing os environment variables

Checklist

• Consider if documentation in docs/ needs to be updated
  • If you've changed the structure of a table, you may need to run generate-md
  • If you've added/removed core study fields that not in US Core, update our list of those in core-study-details.md
• Consider if tests should be added
• Update template repo if there are changes to study configuration in manifest.toml

nit: here and in build_matching_files, I might drop any default argument. Because you pass in prepare and data_path everywhere you call these, and you want to avoid a future bug where a new call to these gets introduced but the dev forgets to pass down the CLI arg.

I'm leaving this in at the main entrypoint since a lot of tests assume it's there, but i've pulled everything downstream
