Migrate to Geocodio API v2 (#11)

Breaking changes (targets release 1.0.0):
- Base URL version prefix changed from v1.11 to v2
  (https://api.geocod.io/v2/).
- Removed the top-level `input` object from /geocode and /reverse
  responses; parsed address now lives in results[].address_components.
- Renamed keys inside address_components and
  address_components_secondary:
  zip -> postal_code, state -> state_province,
  secondaryunit -> unit_type, secondarynumber -> unit_number.

Updated VCR cassettes to v2 URIs and the v2 response shape, updated
spec assertions for the new keys/structure, bumped VERSION to 1.0.0,
and added a CHANGELOG entry.
