Description

Added update spending limit functionality and gave the permission to DAO.
Closes #2

How to test

Use the code below or go to Aragon page and create a proposal using smart contract composer.

import { ethers } from "ethers";
import { DaoAction } from "@aragon/sdk-client-common";
import { hexToBytes } from "./../src/lib/helpers";
