v1.2.0

What's Changed

Added

• viz module with plot_centroiding() for visual inspection of centroiding quality (2x2 panel: raw peaks, centroids, noise-rejected, 1D spectrum comparison).
• plot_centroiding exported from the top-level tdfpy namespace.
• Example DDA and PRM datasets under tests/data/.
• scripts/benchmark_centroiding.py — benchmarks the Numba vs pure-Python centroiding path (~20x speedup on real MS1 frames).

Changed

• Centroiding now uses dynamic IM region growing instead of a fixed-radius tolerance, improving peak grouping for adjacent ion mobility peaks.
• Default im_tolerance changed from 0.05 to 0.1 across all centroiding functions and centroid() methods.

Fixed

• Centroiding edge cases where floating-point precision caused peaks at the exact tolerance boundary to be excluded.
• timsdata.dll now included in wheel artifacts for Windows support.
• Validated SQL table names in convert_table_to_df() against TableNames enum.
• Replaced assert with explicit ValueError in centroiding data integrity check.
• Narrowed overly broad except Exception in Numba fallback paths.
• Improved error message for unsupported platforms in timsdata.py.
• Added minimum version bounds (>=2.0) for numpy and pandas dependencies.
