Fix sign of XAS
There are currently no pipelines.
To run a merge request pipeline, the jobs in the CI/CD configuration file must be configured to run in merge request pipelines and you must have sufficient permissions in the source project.
To get the sign of the XAS right (positive absorption peak) we used to look at the name of the channels.
This MR looks at the sign of the average Io and It signal to determine the correct signs.
Closes #61 (closed)
