bornagain 22.0 (new formula)

[AlQuemiste]

A Homebrew formula is added to build the BornAgain GUI and its related Python wheel.

BornAgain is an open-source research software to simulate and fit neutron and x-ray reflectometry and grazing-incidence small-angle scattering. BornAgain has a GUI which can interoperate with a Python interpreter. It can be also used as a Python package.

• Have you ensured that your commits follow the commit style guide?
• Have you checked that there aren't other open pull requests for the same formula update/change?
• Have you built your formula locally with HOMEBREW_NO_INSTALL_FROM_API=1 brew install --build-from-source <formula>, where <formula> is the name of the formula you're submitting?
• Is your test running fine brew test <formula>, where <formula> is the name of the formula you're submitting?
• Does your build pass brew audit --strict <formula> (after doing HOMEBREW_NO_INSTALL_FROM_API=1 brew install --build-from-source <formula>)? If this is a new formula, does it pass brew audit --new <formula>?

BornAgain v22.0 needs, in particular, libheinz v2.0.1 and libformfactor v0.3.2 (latest versions of the respective libraries).

However, I could not update these libraries via brew bump-formula-pr as they are apparently automatically updated.

For instance, with brew bump-formula-pr libformfactor I get the following error message:

Error: Whoops, the libformfactor formula has its version update

We'd still love your contributions, though, so try another one
that's not in the autobump list:
  https://github.com/Homebrew/homebrew-core/blob/master/.github/autobump.txt

With brew audit --new bornagain, I get the following errors which I cannot resolve:

  * Dependency 'python@3' is an alias; use the canonical name 'python@3.13'.
  * Dependency 'qt@6' is an alias; use the canonical name 'qt'.
  * Files were found with references to the Homebrew shims directory.
    The offending files are:
      share/BornAgain/bornagain_build.log
  * Unexpected universal binaries were found.
    The offending files are:
       ...
  * Libraries were compiled with a flat namespace.
       ...

Reason:
* BornAgain is compatible with Python 3.x with x >= 10 (not just 3.13).
* BornAgain requires Qt6.
* The build log should be included in the distribution and is needed for bug reports.
* BornAgain needs its own Python virtual environment, hence the extra binaries.
* Currently BornAgain libraries do not have a version number. This cannot be changed at the moment.

Thanks for contributing to Homebrew! 🎉 It looks like you're having trouble with a CI failure. See our contribution guide for help. You may be most interested in the section on dealing with CI failures. You can find the CI logs in the Checks tab of your pull request.

I put some comments on the install block, but this is way too much custom logic to be maintainable. Please check other formula to see how formulae usually install python wheels.

Please, do not use puts and odie so much. def install block works only if you build from source, regular Homebrew users will download pre-compiled binaries (bottles in Homebrew terminology) created during CI.

I'd recommend to read docs about Language::Python module: https://rubydoc.brew.sh/Language/Python.html

[AlQuemiste]

Added a numerical test; see revision d0c9522.
Please let me know if any further changes are required.

This still needs a lot of work. Given that it's also not very notable software, I'm not inclined to accept this. Please consider hosting this in your own Homebrew tap instead.
