High Level Overview of Change
This PR adds a pre-commit hook, which runs the clang-format linter locally before a commit is committed.
There are no C++ code changes, just a new YAML file and instructions in the CONTRIBUTING for how to set up the linter.
Context of Change
A pre-commit hook makes it easier to work with the clang-format linter, since it automatically runs before a commit is committed. It is also opt-in (you need to install it for it to do anything).
Type of Change
Test Plan
This was tested locally and worked when I tried to commit a change that didn't satisfy the linter.
I also confirmed that it is indeed using the correct version of clang-format (10.0.1).
