SNC Advanced Electron Density analysis

[SafirZouzout]

Describe the bug

The SNC Advanced Electron Density phantom analysis doesn't seem to work. I saw that you needed data to improve the Cheese module so I sent the dicoms here I believe that the issue might be because this is not the right phantom. When clicking on the link on the pylinac doc this leads to this page but I suspect that the class is designed for this phantom

To Reproduce

I used the following code:

from pylinac import CIRS062M
cheese_folder = r"my_path"
cheese = CIRS062M(cheese_folder)
cheese.analyze()
cheese.plot_analyzed_image()

and got the following message

Detected shift of 8.554868624420408 was >5 degrees; automatic roll compensation aborted. Setting roll to 0.

Expected behavior

Correct placement of the ROIs

Screenshots

Additional context

I wrote this that gives some results, feel free to use it in pylinac if it can be of any help. I know this might not be the place to write some code but I don't feel very confident sending merge requests as I'm not very good at coding.
