Feature suggestion: Allow custom list of hooks to ignore on exhaustive-deps

The `exhaustive-deps` lint rule doesn't require setters from `useState`, dispatch from `useReducer`, and refs from `useRef` in dependencies, because we know for sure those will never change. I'd like to be able to add additional custom hooks to that "safe list". I understand this is potentially very dangerous, but we have a handful of hooks that simply wrap `useRef` with some logic. The returned result is essentially just a `useRef` result, so it's perfectly safe to ignore as a dependency. I'm imagining something like this in the eslint config: ``` { "rules": { // ... "react-hooks/exhaustive-deps": ["warn", { "safeHooks": "(useRefWrapper|useOtherRefWrapper)" }] } } ``` Where `useRefWrapper` might look like so: ``` const useRefWrapper = () => { const ref = useRef(); if (ref.current) { console.log('hi!'); } return ref; } ``` Does this seem like a reasonable option, assuming the documentation has a clear caveat mentioning the dangers? If so, I'm happy to work on implementation.
