Added function to compile queries from matchbox

[wpfl-dbt]

Context

We need to be able to compile queries to SQL so we can quickly assess them on a live database while developing Matchbox. This PR adds a function to compile query() to raw SQL.

Note it doesn't replicate the entire function, as query() needs a data warehouse, but it reproduces the most costly SQL we'll need to run on the server.

Note 90% of this work is plundered from @nimonika 's feature/generate_query_for_benchmarking branch.

Changes proposed in this pull request

• Adds compile_query_sql() and unit test
• Ruff version bump to pass GitHub action. I know this is poor practise but it's not a big PR, please forgive me

Guidance to review

• Verify you're happy that this function reflects the more important functionality of query()
• Verify you're happy with what computation I've chosen to put into this function
