Installing from source is broken

[synapticarbors]

When installing from the source distribution (.tar.gz) rather than the wheel, there is an error due to the readme.md not being in the source distribution:

pip install --no-binary :all: whatlies

Complete output (11 lines):
    Traceback (most recent call last):

        return self._accessor.open(self, flags, mode)
    FileNotFoundError: [Errno 2] No such file or directory: 'readme.md'

I would recommend adding a MANIFEST.in file to specify that the readme is included:
https://packaging.python.org/guides/using-manifest-in/

I've always wondered what those files are for 😅 .

I've just added it to the project, could you confirm if this should suffice? If so I'll push a new patched version.

[synapticarbors]

I think that should work

[koaning]

Grand. I'll be fixing some unit tests and pushing once it's done :)

[koaning]

I just pushed version 0.6.5 with the fix. Thanks for reporting :)

@koaning I had started packaging whatlies for conda-forge and this error happened there. Thanks to @synapticarbors, the root-cause of this error was identified and then it got fixed. The build just passed with the base requirements of whatlies.
