Returns latitude components: degrees, minutes, seconds and optionally
 a hemisphere:

    # Nothern hemisphere:
    g = Geo::Coord.new(50.004444, 36.231389)

    g.latdms        # => [50, 0, 15.9984, "N"]
    g.latdms(true)  # => [50, 0, 15.9984]

    # Southern hemisphere:
    g = Geo::Coord.new(-50.004444, 36.231389)

    g.latdms        # => [50, 0, 15.9984, "S"]
    g.latdms(true)  # => [-50, 0, 15.9984]
