[Feature Request]: Response Creation - Bring back delta KL?

[JoschD]

Feature Description

In the past we could choose between delta K and delta KL, allowing to have equal magnet strengths in the response.

At the moment there is only delta K, because KL needs the info about the magnet lengths as well.

• Ask if this needs to be brought back ?
• Implement delta KL
