Remove the counties and unitary authorities library

It’s been superceded by the ‘Local’ library (formerly ‘Electoral wards
in the United Kingdom’).

The latter is better because:
- it’s covers all 4 nations, not just England and Wales
- it has electoral wards as well as local authorities which group them,
  so there’s more flexibility when choosing an area to broadcast to
