python-matplotlib 3.8.2 (new formula)

[singingwolfboy]

matplotlib is a popular package within the scientific Python community. All of its dependencies are packaged in Homebrew except for Contourpy (see #154705), which is included as a resource instead.

Depends on #154801 in order to use the --no-isolation flag to python-build, which in turn allows us to use the Homebrew-installed build dependencies, instead of python-build downloading and installing them during the build process.

matplotlib will vendor a couple dependencies without some extra workarounds (see #154454 though don't need MPLSETUPCFG env var when already inside the source root as that is default).

Current release needs mplsetup.cfg to use Homebrew copies - https://github.com/matplotlib/matplotlib/blob/v3.8.2/doc/devel/dependencies.rst#use-system-libraries

Future release will need to be passed in as arguments to pip - https://github.com/matplotlib/matplotlib/blob/main/doc/devel/dependencies.rst#use-system-libraries
