- Residual callable is vectorized for easy multithreading by the user. Internally all vectors are now explicitly column vectors.
- Removed central findiff option, it wasn't applicable at the bounds anyway and just complicated the code.
- Added optional user-provided norm function for non-quadratic (robust) norms.
- Added an iter_callback callable for user convenience.
- Added option to internally check user-provided Jacobian and norm against finite differences.
- Updated the notebook accordingly.
