Release v1.0.3

[dahlend]

[v1.0.3]

Added

• Added support for loading orbit information from JPL Horizons
• Added quality of life function to SimultaneousState for computing the RA/Dec along with the projected on sky rates of motion.
• Added more complete testing for light delay computations in the various FOV checks.

Changed

• Changed the return signature for fov_static_check, this now returns indices of the inputs, instead of the original inputs themselves.

Fixed

• Sampling of JPL Horizons orbit fits was slightly off, and appears to be fixed by assuming that the epoch time of the covariance fits is in UTC. This assumption is now included in the covariance matrix sampling. This is different than their other data products.
• Field of View checks for SPK checks was not returning the correct light delayed time, it was returning the position/velocity at the observed position, but the time was the instantaneous time.

Removed

• Removed several polar coordinate transformations in the rust backend which were all equivalent variations of latitude/longitude conversions. Nothing in the Python was impacted.

Main goal for this release is the inclusion of on sky velocity calculations, along with a function to query JPL Horizons for their non-truncated orbital elements (as opposed to the truncated ones provide by MPC).
