TYP: Typing annotations in clipboard

- [ ] tests added / passed
- [x] passes `black pandas`
- [x] passes `git diff upstream/master -u -- "*.py" | flake8 --diff`

Hmm +/-0 on this one. Actually might be nice to do the annotations upstream in pyperclip and vendor down as appropriate rather than us trying to do here agree with @WillAyd that should vendor these, but ok to do both; pls rebase Thanks @MomIsBestFriend really appreciate the PRs. As mentioned if you could do this upstream in Pyperclip would be great as well
