GammaLib

This action seems more to relate to gammalib than ctools. The actual code supports already building for Python 3.9, the current Python version 3.10 should be added.

I first tried building GammaLib for Python 3.9 on my Mac:

$ anaconda
$ conda build dev/conda.recipe --python=3.9

I repeated the check for Python 3.10, and did similar tests for ctools. All worked out fine.

Merged into devel.
