AmSC OpenMetadata - Tiled Sync

1. Find ID token at the bottom of https://my.american-science-cloud.org/profile (after logging in with Globus).

2. Make a .env file (see .env.example) with that ID token and a catalog name.

3. Start a Tiled subscription that sends a POST to OpenMetadata when a new node is created in Tiled's sandbox.

   uv run test.py

4. Then, write to the sandbox like:

   c['tst/sandbox'].write_array([1,2,3], metadata={'color': 'blue', 'mood': 'elated', 'description': 'Time for some American Science, amiright?', 'uid': str(uuid.uuid4())})
