Pyproject.toml & wheel over setup.py

[ryanneilyoung]

when installing this package through CI I see the following warning:

DEPRECATION: starkbank-ecdsa is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at pypa/pip#8559

I see this problem as a problem when attempting it install the package in a python 3.12 environment. This is running a pip install in a python-3-12 slim based docker image.
