Migrate from setup.cfg to pyproject.toml (#48)

* Migrate project metadata from setup.py to pyproject.toml

Define project metadata in pyproject.toml! Required dependencies are now listed under the [project] section instead of in requirements.txt. Versioneer config has also been moved from setup.cfg to [tool.versioneer].

* Fix check on sdist version number

Package name is cupy_xarray, not cupy-xarray.

* Include optional test dependencies in pyproject.toml

Remove requirements_test.txt file, moving the test dependencies to pyproject.toml instead. Also updated MANIFEST.in to remove the requirements.txt entry.

* Keep setup.py with versioneer.get_version() and .get_cmdclass()

Still need these two lines so that the sdist won't have a 0.0.0 version. Xref https://github.com/python-versioneer/python-versioneer/blob/0.29/INSTALL.md#common-steps
