Support for forEachRight

[haejunejung]

Hello,
If you need loadsh's forEachRight function, Can I work it?

If it is okay to proceed, lodash's forEachRight supports both Array and Object, but in [#91], I would like to ask if it is only necessary to implement array in the array category.

Sure! I think we might just implement it for arrays.

I've implemented a forEachRight function:

export function forEachRight<T>(arr: T[] = [], callbackfn: (value: T, index: number, arr: T[]) => void): void {
  for (let i = arr.length - 1; i >= 0; i--) {
    const element = arr[i];
    callbackfn(element, i, arr);
  }
}

If this implementation looks good, may I proceed with enhancing the documentation and tests, and then submit a pull request?

Looks great! What about renaming callbackfn to callback? (It seems that it is shorter, and it does not lose a lot of meaning.)

Oh, I think the code you suggested is better too.
Thanks for your help 👍
