Improve CODEOWNERS file #443
Description
Over time as more people have gotten involved with this project and more features have gotten added, certain people have become the "expert" at certain parts of the codebase. It no longer makes sense for me to be the sole owner of all of the code in the CODEOWNERS file.
Getting nominated as an "owner" in this file automatically nominates you as a reviewer for a PR in which this file changes.
I would like to update this file to more accurately reflect who best understands which pieces of code.
