Auto assign GitHub issues with a "take" message

[MrPowers]

Some repos are setup so users can type "take" and an issue is auto-assigned to them.

See this pandas issue for example.

This could be a nice addition to this project.

As far as I can tell this only works for people already in the GitHub organization. You cannot assign people outside the organization to an issue

[MrPowers]

@rtyler - I don't think you can assign people outside an organization till they comment on the issue. I was thinking that if they comment "take" and then the GitHub Action callback runs, then perhaps that person can be assigned. Thoughts?

Here's the code.

Someone who understands this better than me can better assess.
