Broadcastable Pseudorange calculation

[dominformant]

In my opinion, it would be preferable to broadcast a function get_pseudo_range over the sat_states instead of looping inside the function pseudo_range.

PositionVelocityTime.jl/src/pseudo_range.jl

Lines 17 to 36 in 4ed3a0f

	function pseudo_ranges(
	sat_states::AbstractVector{SatelliteState{Float64}}
	)
	for i in 1:length(sat_states)
	is_sat_healthy_and_decodable(sat_states[i].decoder_state) || throw(BadData("SV not decoded properly, #decoder: " * string(i)))
	end
	N_sats = length(sat_states)
	c = sat_states[1].decoder_state.constants.c
	times = map(i -> calc_corrected_time(sat_states[i]), 1:N_sats)
	t_ref = maximum(times)
	τ = map(i -> t_ref - times[i], 1:N_sats)
	pseudoranges = τ .* c
	return pseudoranges
	end
