Split CNR visualization in two parts

[lukasbehammer]

Feature Request

Description

Split the visualization for CNR in two parts. One part is for signal visualization, one part for background visualization.

Use cases

This improves performance for the interactive visualization, since only the part that changes on the input has to be reloaded.

Possible implementation

Currently the visualization is a subplot. This can be changed to two single plots. The interactive visualization should be changed accordingly.
