Add Github Issue Templates (#1367)

* Path intersection was not checking paths with circles.

As an optimization the path intersection was checking the paths had three or more elements, caliming that otherwise there was nothing to fill. However a semi circle would actually contain 2 points.

Fixes #1048.

This adds a simplified test case for the 2 offending files reported in the issue.

* Add issue templates

We add issue templates for:

- Bug Reports
- Feature Requests
- Plugin Requests
- Pull Requests
- Questions

* Add Github issue templates

Fixes #1364, but is is missing the template for pull requests see
https://docs.github.com/en/github/building-a-strong-community/creating-a-pull-request-template-for-your-repository

* fix

* Use "New plugin" label
