deprecate loadable util

[dai-shi]

loadable is deprecated infavor of unwrap.

Userland implementation of loadable:

function loadable(anAtom) {
  const LOADING = { state: 'loading' }
  const unwrappedAtom = unwrap(anAtom, () => LOADING)
  return atom((get) => {
    try {
      const data = get(unwrappedAtom)
      if (data === LOADING) {
        return LOADING
      }
      return { state: 'hasData', data }
    } catch (error) {
      return { state: 'hasError', error }
    }
  })
}

Should we deprecate loadable now?

[dai-shi]

I was thinking of doing it with another step, but yeah we can do that now. Let me try.
