Can't pip install

[mileslucas]

For whatever reason, on a clean image I cannot pip install extinction. MWE

$ docker run --rm -ti python bash
/# pip install extinction
Collecting extinction

I had opened #14 because I thought pyproject.toml was simply missing the build-backend key, but I've realized that any local install of the package will work. I tried the following all with success

$ pip install git+https://github.com/kbarbary/extinction#egg=extinction
$ git clone https://github.com/kbarbary/extinction && pip install extinction/
$ echo 'build-backend = "setuptools.build_meta"\n' >> extinction/pyproject.toml && pip install extinction/

I think the problem might be that pyproject.toml needs to be added to MANIFEST.in. I'll check when I'm back at a computer.

Perhaps this does need the build-backend="setuptools.build_meta". Perhaps this is because there is a discrepancy between python setup.py sdist bdist_wheel and python -m pep517.build --source --binary and the latter is required.

I released a new pypi version 0.4.2 which I think fixes the issue (the toml file and the Cython sources were not included in the source distribution in v0.4.1). Can you try again?

Works for me now! Thanks for the help and the release!
