Comment warning about corrupt OpenADAS data

[roni-maenpaa]

Hi,

The comment below warns users about corrupt OpenADAS-data:

core/cherab/openadas/repository/create.py

Line 154 in 547e7d3

# (nitrogen, 2, 'adf15/pec96#n/pec96#n_vsu#n2.dat'), #TODO: OPENADAS DATA CORRUPT

Installing the file in question to the repository works without issues, so I wonder if the problem is with the reliability of the numerical data, or perhaps some other kind of issue?
