Support py3.11

[casperdcl]

Maybe as easy as updating https://github.com/TomographicImaging/CIL/blob/master/recipe/conda_build_config.yaml to remain compliant with SPEC 0

[paskino]

As easy as that, but we'll have to propagate the support to tomophantom, tigre and ccpi-regulariser,

See the test requirements in the conda recipe:

CIL/recipe/meta.yaml

Lines 39 to 46 in 12e45d3

	- python-wget
	- cvxpy # [ linux ]
	- scikit-image
	- tomophantom=2.0.0 # [ linux ]
	- tigre=2.4 # [ not osx ]
	- packaging
	- ccpi-regulariser=22.0.0 # [ not osx ]
	- astra-toolbox>=1.9.9.dev5,<2.1

mamba create -n test_build -c conda-forge python=3.11 'astra-toolbox<2.1'
Looking for: ['python=3.11', "astra-toolbox[version='<2.1']"]

...

Encountered problems while solving:
  - package astra-toolbox-2.0.0-py310h47f459b_1 requires python >=3.10,<3.11.0a0, but none of the providers can be installed

With our current requirements we can't release tested binaries for cil with python 3.11. This means we have to update support to astra-toolbox 2.1 first. #1436
