QML on Apple silicon

[viniavila]

Is there a way to build this into a MacBook Air with Apple Silicon (M1)? I'm trying, but there were a lot of errors complaining
the lack of a FORTRAN compiler. Here is my output of python setup.py build --help-fcompiler

It's worth to mention that I have `gfortran` installed from `brew`, and an Anaconda environment with many tools, including `pip`.

Please note that further development for the QML package is now happening on the qmlcode/qmllib repository. qmllib is a port of the QML's Fortran core functionality with fewer dependencies and numpy 2.0 compatibility. You are encouraged to open any future issues or pull requests there.
