Install dependencies when install dgl-lifesci

Issue #207

Description of changes: With the pyproject.toml, one can run python3 -m build to generate the whl file. When installing that file, all the dependencies would also be installed.

There are yet another step, which is upload the whl file to PyPI. I would wait until receive the approval of the maintainers before continue.

How it was tested

• python3 -m pip install --upgrade build

I see, thanks. Is this repo still maintained?

As I was the only maintainer, I don't think it is still maintained. Most functionalities should still work though. If you need to make any changes, just work on your own fork.
