Add support for finding dead code

[cjgrady]

Is your feature request related to a problem? Please describe.
We want to make sure that we remove any code that is obsolete or no longer used to prevent vulnerabilities or just code bulk.

Describe the solution you'd like
There are tools like Dead and Vulture as well as others that can do this and could be attached as pre-commit hooks and could be included at release GitHub actions as well.

Describe alternatives you've considered
I have tried to manually do this in the past and a tool sounds like a better solution.
