Full api reference

[MSVermet]

1. Added the automatically generated api reference for all modules, functions, and classes to the developer reference section under API reference (issue Add full API reference to documentation #404). Left the other API reference sections untouched.

Is it useful to keep the other API reference sections as well? Or shall I remove those and only have the full api reference there?

2. And updated the license part in the toml (issue pyproject.toml update license #409)

There seems to be a problem with setuptools version and the new standard format for license in the toml. Currently the toml has requires = ["setuptools==75.8.0".... If I change this to setuptools>=75 it is not failing anymore. But I'm not sure if this would break anything.

That's really nice, thanks! The structure is a little too hierarchical though, especially the demo module, which is quite nested. Also it shouldn't start at the metasyn level, but one higher. Also, if you could find how to remove the duplicate reference errors, that would be nice!
