Return object example uses wrong signature

[ryanford]

import { h } from "some-framework"
import picostyle from "picostyle"

const returnObject = true
const { style, css } = picostyle(h, returnObject)

should be:

import { h } from "some-framework"
import picostyle from "picostyle"

const options = { returnObject: true };
const { style, css } = picostyle(h, options)
