I want to be able to import a dataset from Earthmover/Arraylake into my project

https://app.earthmover.io/marketplace

These datasets have versions, like Git refs, so we can use them in pipelines and compute staleness, auto-update from source, etc.

Start with the linked Earthmover marketplace and investigate how Arraylake datasets and their Git-like versions can be represented in this project. No files or tests are named; define the import entry point and verify that version tracking supports pipeline staleness and source updates.
