You have not specified your build dependencies which is required now due to build isolation, testing your repo I was able to make a pyproject.toml with just the following contents:

[build-system]
requires = ["setuptools", "numpy", "Cython"]

And it was able to install your package.

You may want to re-look at the canonical tutorial of specifying a package as best practices have updated over time (FYI I am not an expert I just recognized your error): https://packaging.python.org/en/latest/tutorials/packaging-projects/
