- Python port of NanoLocz level_weighted.m for AFM images and stacks - Supports region-weighted methods: 'plane', 'line', 'med_line', 'med_line_y', 'smed_line' - Implements polynomial and median-based background subtraction with per-region weighting - Handles 2D images and 3D stacks - Includes robust handling of masks, small regions, and degenerate cases - Preserves MATLAB-like centering and scaling for polynomial fits - Compatible with NumPy/SciPy ecosystem; ready for integration into NanoLocz workflow Also add typing to satisfy mypy.

This PR introduces a new module, level_weighted, providing weighted-region AFM image flattening and background leveling routines. The module is a Python port of the Nanolocz-lib MATLAB level_weighted.m used in the NanoLocz workflow and implements region-wise polynomial and median-based background estimation.
https://github.com/George-R-Heath/NanoLocz-Matlab-Library/blob/main/NanoLocz-lib/level_weighted.m
Supported levelling methods include:
The module supports masked images, handling multiple regions with weighted aggregation, and is compatible with both 2D images and 3D stacks.
