Is your feature request related to a problem? Please describe.
Manually formatting code is a large pain.

Describe the solution you'd like
Using clang format to auto format all of our files similar to what we are doing in core.
I believe this would involve:

• Running clang-format on all of our plugins and examples.
• Adding npm run format to dev-scripts.
• Adding npm run format in dev-create.
• Adding a github action to check that code has been formatted properly. Reference in core.
