Note

Bumps to 0.4.2, adds a safety check for empty time differences in CGMS2DayByDay dt0 inference, and updates .gitignore.

• Core logic:
  • iglu_python/utils.py: In CGMS2DayByDay, add a guard to raise ValueError when time_diffs is empty before inferring dt0.
• Packaging/metadata:
  • pyproject.toml: Bump project version to 0.4.2.
• Repo hygiene:
  • .gitignore: Ignore notebooks/test.ipynb.

Bug: Lock file incorrectly includes pyarrow as dependency

The lock file adds pyarrow as a main dependency despite it being removed from pyproject.toml dependencies. Line 631 lists pyarrow in the main dependencies array, and line 680 includes it in requires-dist without an extra marker, making it a required runtime dependency. This contradicts the PR's goal of removing pyarrow from main dependencies and keeping it only as an optional dev dependency, causing users to install it unnecessarily.
