Dedup pip dependencies #23

Closed seanxwzhang closed 4 years ago

This PR tries to address https://github.com/ali5h/rules_pip/issues/22.

The underlying issue is that wheel allows the existence of duplicate dependency specification so long as there's different version constraints. For example,

Requires-Dist: pytest (>=3.6)
Requires-Dist: Flask
Requires-Dist: Werkzeug (>=0.7)
Requires-Dist: pytest

This is a valid specification.
