What does this PR do ?

Implement natural cardinal verbalization for up to 3-digit address numbers.

Before your PR is "Ready for review"

Pre checks:

  • Have you signed your commits? Use git commit -s to sign.
  • Do all unittests finish successfully before sending PR?
    1. pytest or (if your machine does not have GPU) pytest --cpu from the root folder (given you marked your test cases accordingly @pytest.mark.run_only_on('CPU')).
    2. Sparrowhawk tests bash tools/text_processing_deployment/export_grammars.sh --MODE=test ...
  • If you are adding a new feature: Have you added test cases for both pytest and Sparrowhawk here.
  • Have you added __init__.py for every folder and subfolder, including data folder which has .TSV files?
  • Have you followed codeQL results and removed unused variables and imports (report is at the bottom of the PR in github review box) ?
  • Have you added the correct license header Copyright (c) 2023, NVIDIA CORPORATION & AFFILIATES. All rights reserved. to all newly added Python files?
  • If you copied nemo_text_processing/text_normalization/en/graph_utils.py your header's second line should be Copyright 2015 and onwards Google, Inc.. See an example here.
  • Remove import guards (try import: ... except: ...) if not already done.
  • If you added a new language or a new feature please update the NeMo documentation (lives in different repo).
  • Have you added your language support to tools/text_processing_deployment/pynini_export.py.
