Allow passing read functions as props

[boar-is]

To not create boilerplate intermediate atoms:

import { atom } from 'jotai'
import { jotai } from 'jotai-components'

const widthAtom = atom(100)

function Parent() {
  return (
    <jotai.div $style={(get) => ({ width: get(widthAtom) })}>
      example
    </jotai.div>
  )
}
