Climlab

Major update including
- Vastly improved,simplified and **consistent** interfaces for the CAM3 and RRTMG radiation modules
- Better testing
- Better documentation
- More robust build procedure

New features include:
- The RRTMG radiation scheme
- A much-improved build process for the Fortran extension (build once at install time with `python setup.py install`, no need to rebuild for different grid dimensions)
- numerous enhancements and simplifications to the API.

This is a bug fix release to correctly expose constants defined in the Fortran code to the Python wrapper.

What's Changed
* Expose constants to Python by brian-rose in https://github.com/climlab/climlab-rrtmg/pull/34


**Full Changelog**: https://github.com/climlab/climlab-rrtmg/compare/v0.4...v0.4.1

This release modernizes how we compile the Fortran code and build the installable Python package, now using meson.

As a consequence of this change, it will now finally be possible to run the RRTMG code under recent Python version (3.12, 3.13).

What's Changed
* Another meson build attempt by brian-rose in https://github.com/climlab/climlab-rrtmg/pull/31
* working build python3.10 ubuntu by dorrih-stardust in https://github.com/climlab/climlab-rrtmg/pull/29

New Contributors
* dorrih-stardust made their first contribution in https://github.com/climlab/climlab-rrtmg/pull/29
