Error handling for CubeFactory and TicaCubeFactory

[jaymedina]

Summary

Currently the errors that get returned when SPOC FFIs are fed into TicaCubeFactory and vice versa are vague and not helpful to the user. This PR updates the error handling by raising an error when the wrong type of FFI is fed into either CubeFactory or TicaCubeFactory to make TESS cubes.
