BUG: Issues installing apexpy in python 3.12

[ljlamarche]

Describe the bug

Apexpy fails to install in a new python python 3.12 environment. The traceback (provided in full below) suggests this is the main error

ERROR: Could not build wheels for libcst, which is required to install pyproject.toml-based projects

and it may be related to there not being a Rust compiler available.

To Reproduce

1. Create new python 3.12 environment
2. pip install apexpy

Expected behavior

Sucessful installation of apexpy.

                    ############################
                    # Package would be ignored #
                    ############################
                    Python recognizes 'libcst.tests.pyre' as an importable package[^1],
                    but it is absent from setuptools' `packages` configuration.
      
                    This leads to an ambiguous overall configuration. If you want to distribute this
                    package, please make sure that 'libcst.tests.pyre' is explicitly added
                    to the `packages` configuration field.
      
                    Alternatively, you can also rely on setuptools' discovery methods
                    (for example by using `find_namespace_packages(...)`/`find_namespace:`
                    instead of `find_packages(...)`/`find:`).
      
                    You can read more about "package discovery" on setuptools documentation page:
      
                    - https://setuptools.pypa.io/en/latest/userguide/package_discovery.html
      
                    If you don't want 'libcst.tests.pyre' to be distributed and are
                    already explicitly excluding 'libcst.tests.pyre' via
                    `find_namespace_packages(...)/find_namespace` or `find_packages(...)/find`,
                    you can try to use `exclude_package_data`, or `include-package-data=False` in
                    combination with a more fine grained `package-data` configuration.
      
                    You can read more about "package data files" on setuptools documentation page:
      
                    - https://setuptools.pypa.io/en/latest/userguide/datafiles.html
      
      
                    [^1]: For Python, any directory (with suitable naming) can be imported,
                          even if it does not contain any `.py` files.
                          On the other hand, currently there is no concept of package data
                          directory, all directories are treated like packages.

            error: can't find Rust compiler
      
            If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it. Installing from the wheel would avoid the need for a Rust compiler.
      
            To update pip, run:
      
                pip install --upgrade pip
      
            and then retry package installation.
      
            If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain.

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