ALTRIOS 1.0.0.

[calbaker]

New Features

• TrackedState to ensure that each state variable is updated once and only once in each time step unless we deliberately override that behavior, which is necessary in a few edge cases
• no more direct variable access to Rust struct fields -- use to_pydict() and from_pydict() methods instead because these provide a much cleaner user experience
• nearly everything that can/should be synchronized now is synchronized with fastsim-3, making for easier back-and-forth improvements and a platform for eventually transitioning to a common dependency crate for both FASTSim and ALTRIOS
• improvements to hybrid locomotive controls
• streamlined calibration/validation framework with working demonstrations
• mandatory units in all yaml files, e.g. length: ... becomes length_meters: ...

PRs to Complete First
