get_all_sat_info speed

Is `get_all_sat_info()` capable of returning sat states for multiple epochs at once? I am looking to develop a GNSS simulation and couldn't figure out a way to do so (other than a list comprehension).

I may have overlooked something in the examples.

Start by reading the get_all_sat_info() entry point and the examples referenced in the issue. Determine whether the current API accepts multiple epochs and, if not, clarify the expected batch behavior and GNSS simulation use case before identifying implementation and test locations.
