RIOT PR Checklist

Ensure the PR passes these tests:

make buildtest -- Builds for all boards. Run in example directory. Not sure if changes must be committed before running.

CI_BASE_BRANCH=master make static-test -- Various tests. Run in top level directory. Changes must be committed to feature branch before running.

WARNING: If your work is based on unmerged commits from another PR, use the branch for that PR as CI_BASE_BRANCH.
