codespell_lib/tests/ → tests/

Source distributions such as sdist must include test directories.
Note that all files matching the pattern `test/test*.py` (or perhaps
`tests/test*.py` with an `s`?) are included implicitly:
	https://packaging.python.org/guides/using-manifest-in/#how-files-are-included-in-an-sdist

Binary distributions such as wheel must exclude test directories.
This seems to be done implicitly for top-level `tests/` directories
only. I do not know how to explicitly exclude files from binary
distributions. This setuptools issue might be of interest:
	pypa/setuptools-scm#190

I change `codespell_lib/tests/` to a top-level `tests/` directory as
a workaround. Not that I like it, but I currently lack an alternative.

Fixes (partially) codespell-project#2592.
