Full Vectorization of Solar Azimuth and Elevation Estimation

sun_postion by Vicent Roy vectorization in both time and location

The excellent sun_position utility by Vincent Roy has been converted to an alternate library that accepts a [1XN] Julian vector in place of [Y,D,M,H,MI,S] and local hour offset and/or a [3XN] position vector in place of the location structure. Calculations with fixed time and varying location or fixed location and varying time can be used. Varying time and position calculations are suited for aircraft or satellite observations.
