Arguments now a single object

Is there anything in the PR that needs further explanation?

As the arguments have grown over time the hook is getting trickier to use. This change lets you pass in a configuration object with named variables rather than a long list of arguments.

This allows you for example use the first and last argument (how it was) without needing to specify the middle arguments.

E.g. Old Way:

const { data, loading, error, refresh } = useApi(
  "https://some-api.com",
  0,
  null,
  "get",
  myChangedCallback
);

New way:

const { data, loading, error, refresh } = useApi({
  apiEndpoint: "https://some-api.com",
  changed: myChangedCallback
});
