@ltiffanydev I closed & reopened this PR to force the CLA bot to run again and it looks happy now.

One change you'll need to make on this PR is target it for the development branch instead of master.

Also, the style and mypy checks are failing; see the developer guide for getting those cleaned up on your branch.

@ltiffanydev reminder when you merge this to use the "squash and merge" option to bring all these commits into one. I think that might be the default anyways.

Also, you can ignore the failing License Compliance check. It's happening to all PRs on TSC at the moment.
