Enhacement to method hook to use react-script-hook

[aoloo]

I was able to get the link element to load by utilizing react-script-hoo. This implementation simplifies the code and makes it super easy to dynamically load an external script and know when it is loaded.

export function useMethod(opts: IElementClientOptions): IElementClient | null {
  const [loading] = useScript({
    src: 'https://static.methodfi.com/elements/v1/stable/init.js',
    checkForExisting: true,
  });

  // @ts-ignore
  return !loading ? new window.Method(opts) : null;
}
