Tutorial notebook isn't work well because of peptide column

[elephantoid]

Describe the bug
I was going to learn how to use oktoberfest using your tutorial notebook.
but it has a problem about column names.
i also can't find "peptide" anywhere even i downloaded zip file('https://zenodo.org/record/7613029/files/Oktoberfest_input.zip')

anyway, i checked runner.py and there is the point.
peptides_spectral_library.csv(from zenodo) columns are [modified_sequence, collision_energy, precursor_charge]
there is no peptides! so L304 of runner.py have to occur KeyError

To Reproduce

Steps to reproduce the behavior:

1. setup conda environment using script.
2. make a new jupyter notebook
3. copy & paste each cell from Tutorial

Expected behavior

The above exception was the direct cause of the following exception:
