Support for Python 3.12.3

[jckitch]

I run into challenges installing space on my computer when using the newest version of Python (3.12.3). It seems to be related to the installation of pyproj version 3.4.1. pip runs into a compile error when it tries to install pyproj 3.4.1 in the Python 3.12 folder, entire error message attached below. The newest version of pyproj 3.6.1, the newest version, installs without any problems but can't be used by space which requires 3.4.1. The full error message is an attachment to this issue, an abbreviated message highlighting (potentially) the most important parts is below.

pip install "git+https://github.com/NSAPH-Projects/space@dev#egg=spacebench[all]"

  note: This error originates from a subprocess, and is likely not a problem with pip.

I also get this error when I try to install the "base" version of space, i.e. with pip install space bench[all].
