feat: update State printing to support extended state

[kyle-cochran]

When printing the State, you currently see:

-- Trajectory :: State -----------------------------------------------------------------------------
    Instant:                                 2018-01-01 00:00:00 [UTC]                
    Position:                                [1.200000000000, 3.400000000000, 5.600000000000] [m] @ GCRF 
    Velocity:                                [7.800000000000, 9.000000000000, 1.200000000000] [m/s] @ GCRF 
----------------------------------------------------------------------------------------------------

This updates the print to support extending the state beyond position/velocity. So now it looks like:

-- Trajectory :: State -----------------------------------------------------------------------------
    Instant:                                 2018-01-01 00:00:00 [UTC]                
    Frame:                                   GCRF                                     
    CARTESIAN_POSITION                       [1.2000, 3.4000, 5.6000]                 
    CARTESIAN_VELOCITY                       [7.8000, 9.0000, 1.2000]
