Fix hardcode magnitude column names

[hdante]

Hello, when running an estimation with a file using different column names for the magnitudes, I get the following error:

Process 0 running estimator on chunk 0 - 1561
Traceback (most recent call last):

KeyError: 'mag_u_lsst'

I'm passing with the common parameters the correct name ("mag_u").

• I have described the situation in which the bug arose, including what code was executed, information about my environment, and any applicable data others will need to reproduce the problem.
• I have included available evidence of the unexpected behavior (including error messages, screenshots, and/or plots) as well as a descriprion of what I expected instead.
• If I have a solution in mind, I have provided an explanation and/or pseudocode and/or task list.

Hi thanks for the issue. I think I have already fixed this by looping over the bands parameter. This should be merged soon.

I will close when we merge #27
