fix types on resultFunc (#591)

[bdwain]

Fixes #591

Happy to make tweaks to this, but I think it's roughly what is needed to fix the broken types

From original issue.

I think there are incorrect types for the resultFunc property that you can pull off of a created selector. I am on version 4.1.7

function isOdd(num: number): boolean {
  return num % 2 === 1;
}

const memoizedIsOdd = createSelector([isOdd], (bool: boolean) => bool);

memoizedIsOdd.resultFunc(true).clearCache(); //doesn't exist, but the types think it does

clearCache is only on the actual selector returned by createSelector, not the return value of result func. The types think it's on both though.

node output:

Welcome to Node.js v16.18.1.
Type ".help" for more information.

Seems reasonable at first glance. Thanks!

I'll try to publish a new version no later than this weekend.
