py-hyperlink: updated to 20.0.1

20.0.1
Rerelease to fix packaging metadata around conditional requirements.

20.0.0
* CPython 3.7 and 3.8 and PyPy3 added to test matrix
* Hyperlink now has type hints and they are now exported per
  [PEP 561](https://www.python.org/dev/peps/pep-0561/).
* Several bugs related to hidden state were fixed, making it so that all data
  on a `URL` object (including `rooted` and `uses_netloc`) is reflected by and
  consistent with its textual representation.
  This does mean that sometimes these constructor arguments are ignored, if it
  would create invalid or unparseable URL text.
