Delegate specified instance method to the registered FFI delegate. @note It only takes one method name so it's easy to add some
documentation for each delegated method.
@param method [Symbol] method to delegate @return [void]

Allocates a new instance and attaches the FFI delegate to it. This is useful if you already have an FFI delegate and need to attach it to a fresh high-level object. @return [CZTop::*] the fresh object @note initialize won't be called on the fresh object. This works around
the fact that #initialize usually assumes that no FFI delegate is attached yet and will try to do so (and also expect to be called in a specific way).
