Improve handling of vehicle loads in SimulateECSRun, other small changes

[jzuhone]

Description

SimulateECSRun has handling to simulate a LTECS run for vehicle loads, but unfortunately it does not handle the case where the run begins during one vehicle load and continues into the following load (also vehicle-only). The simplest solution to this problem is to use kadi to obtain the commanded states for vehicle loads. This will simply grab all of the commanded attitudes that have been entered into the database, which occurs shortly after loads are approved. The code will print to the log what loads were used in constructing the states.

There is an interface impact as a result of these code changes (see below).

This PR also removes the code specific to the focal plane model that checked violations of the science data quality limits during a LTECS measurement--this is largely beside the point these days. For that reason we no longer need to specify the "instrument" when running the model for the ACIS FP.

Interface impacts

The accepted value to use for specifying the vehicle load option to the attitude argument in SimulateECSRun has changed. Previously, one gave as the value the name of the load to take the commands from. Now, to specify vehicle commands, simply specify "vehicle" as the argument.

Ran the command line version (simulate_ecs_run) using the same conditions as the recent LTECS run on 2024:160.

Looks OK to me.

Looks fine
