[2025-10-15-MDL] Train on new addresses

[mdeylessard]

Overview

Brief description of what this PR does, and why it is needed.

Using usaddress (0.5.16) in a BigQuery UDF and noticing inaccurate parsing of addresses with the following patterns:

• Multi-word street names, particular if name contains more than one street suffix
• Occupancy types of "basement" and "trailer"
• Occupancy identifiers of "upper," "lower," and "ground"

Testing

• 3 iterations of labeling and training real and mock addresses
