Warnings with new array dispatch functionality in casadi 3.8.0 #91

tests/test_trajectory_analysis.py: 4 warnings
  /Users/krlyons/proj/condor/condor/.venv/lib/python3.13/site-packages/casadi/casadi.py:913: FutureWarning:
  casadi: a numpy function was called on a casadi value (issue #2959).
  This used legacy casadi 3.7.2 behaviour, where the result type follows
  the input:
    - a numeric input (DM)       -> a plain numpy array
    - a symbolic input (SX / MX) -> a casadi value, or an error if the
                                    function has no casadi equivalent

  For a shape-correct, type-preserving result, opt in to the
  casadi-aware numpy support:

      try:
          ca.GlobalOptions.setNumpyMode(1)
      except AttributeError:
          pass

  Or use setNumpyMode(-1) to keep legacy behaviour silently.
  Shown once; run python with -W always to see every occurrence.
