This wrapper caches the result of `plugin.function_exists`, to avoid having to load a plugin from the pool every single time just to find out if the given function exists. It can improve performance if there are many plugin hooks without corresponding plugin functions. --------- Co-authored-by: zach <zach@dylibso.com>
