/**
* Like `useEffect` but its callback is invoked only if all given conditions match a given predicate.
*
* @param callback Function that will be passed to the underlying effect hook.
* @param deps Dependency list like the one passed to `useEffect`. If not
* `undefined`, the effect will be triggered when the dependencies change and the given `conditions`
* satisfy the `predicate`.
* @param conditions List of conditions.
* @param predicate Predicate that should be satisfied by every condition in `conditions`. By
* default, the predicate checks that every condition in `conditions` is truthy.
* @param effectHook Effect hook that will be used to run `callback`. Must match the type signature
* of `useEffect`, meaning that the `callback` should be placed as the first argument and the
* dependency list as second.
* @param effectHookRestArgs Extra arguments that are passed to the `effectHook` after the
* `callback` and the dependency list.
