py-matplotlib-venn: updated to 1.0.0

Version 1.0.0

- Fixed package installation issues.

Version 1.0.0-alpha

- Dropped support for Python versions below 3.5 (by excluding those versions \ 
from CI builds)
- Added typing annotations. Some arguments are now a bit more strictly typed.
  E.g. what previously would accept a List now requires (at least as far as type \ 
annotations are concerned) a tuple.
- Refactored the code by abstracting away the layout algorithms to allow plug-in \ 
customization.
  This deprecated the `normalize_to` input argument to the venn2 and venn3 \ 
functions, and made
  `venn2_unweighted` and `venn3_unweighted` obsolete. These will be removed in \ 
some future version.
