v3.0

First pyhgtmap release after fork from phyghtmap.

What's Changed

• Fixed compatibility issues with recent matplotlib and GDAL (dropping compatibility with legacy matplotlib versions)
• Added unit test for most features
• Refactored output modules (including relying on official pyosmium library to write pbf format)
• Massive performance improvements (using efficient parallelization, better contour simplification algorithm)
• Removed support for single file output (getting rid of lot of code complexity and allowing better parallelization)
• Experimental contour smoothing by super sampling of input data
• Use hatch for package development
• Publication on PyPi

Full Changelog: v2.23...v3.0

Quick benchmark of performances improvements

Testing against France PACA dataset, on Intel 13600K under Windows WSL1. Files are already downloaded from previous run (just comparing transformation to OSM PBF format).
