Update install

[cmbant]

Below is the trace I get doing a default install on py12. It does work if I use pip install --use-pep517. You may need to update to .toml etc system (not sure what the error actually is).

That seems like an issue with the installer script for sacc, it says it crashes on the setup file for sacc? Can you try manually installing sacc? Googling similar problems suggests it may also be an issue with the version of setuptools you have installed?

[cmbant]

I can't reproduce an issue with sacc. Maybe the working install updated some relevant package. Now if I try to install ACT again without the extra command line I just get warning
DEPRECATION: Legacy editable install of ACT-DR6-CMBonly==1.0.0 from file:///mnt/pact/al323/git/DR6-ACT-lite (setup.py develop) is deprecated. pip 25.1 will enforce this behaviour change. A possible replacement is to add a pyproject.toml or enable --use-pep517, and use setuptools >= 64. If the resulting installation is not behaving as expected, try using --config-settings editable_mode=compat. Please consult the setuptools documentation for more information. Discussion can be found at https://github.com/pypa/pip/issues/11457

Hmmm, this is strange. I am not sure what to do about this. I will try to put the package on pypi next week, hopefully that will avoid these installation difficulties in the future.

Probably making a simple toml would be sufficient, don't see similar errors with camb/getdist since adding one.
