Adds a tutorial for extracting the top quark mass and jet energy scale

  • generate 2D templates with top mass shift and JES systematic
  • plot variations (1D and unrolled)
  • fit + diagnostics similar to tutorial 1

Adds a new Jupyter notebook `notebooks/tutorial_3_top_mass.ipynb` that demonstrates how to extract a parameter like the top quark mass from an invariant mass distribution using `rabbit`. The notebook generates pseudo-data, writes the tensor with the mass shift mapped as an unconstrained shape systematic, and runs the fit. Links the new tutorial in `README.md`.

Also includes the same tutorial as a python script in `notebooks/tutorial_3_top_mass.py`.

Updates `notebooks/tutorial_3_top_mass.ipynb` and `notebooks/tutorial_3_top_mass.py` to use a 2D invariant mass distribution (reconstructed W mass vs. reconstructed top mass). The fit now extracts the top mass shift as an unconstrained parameter while simultaneously fitting the Jet Energy Scale (JES) uncertainty as a constrained systematic shape variation that affects both the W mass and top mass.
