Delete setup.py, MANIFEST.in and move configuration to pyproject.toml

[gsheni]

• Delete setup.py and move some configuration to pyproject.toml

With the release of pip v19.1.1 , editable installs are again allowed in the presence of pyproject.toml.

• Additionally, deleted MANIFEST.in because of the following:
  • https://packaging.python.org/en/latest/guides/using-manifest-in/#how-files-are-included-in-an-sdist
• following files are included in a source distribution:

  all files specified by the package_data and data_files setup() arguments
  the file specified by the license_file option in setup.cfg (setuptools 40.8.0+)

• deleted codecov because we don't actually use it

[rwedge]

The oldest pip version I could get to make an editable install was 21.1, if that makes any difference

[gsheni]

@rwedge I think that is fine.

I also deleted Manifest.in, see my comment on PR desc.

[gsheni]

@rwedge @thehomebrewnerd ready for review

[rwedge]

Looks good, assuming tests pass

[thehomebrewnerd]

Looks good to me. I tested both building and installing locally and all seemed to work as expected.
