v1.2.0

Fixed

• get_times no longer raises Math::DomainError for polar latitudes.
  Previously, calling get_times for any location and date where the sun
  did not cross a given altitude (polar day, polar night, or any partial
  case) would crash the entire call with an unhandled Math::DomainError
  from Math.acos. This bug has been present since the original 2015
  port. Events that don't occur are now reported as nil in the result
  hash, mirroring the sparse-result pattern already used by
  get_moon_times.

Added

• :always_up and :always_down flag keys on the get_times result.
  When neither sunrise nor sunset occurs, the result hash includes either
  :always_up => true (midnight sun — sun above horizon all day) or
  :always_down => true (polar night — sun below horizon all day). The
  flag is determined from the sun's altitude at solar noon. Other events
  in the same call (:solar_noon, :nadir, and twilight boundaries that
  do still occur) are returned normally alongside the flag.
