Add option to configure update step
Is your feature request related to a problem? Please describe. Would like to configure the update step by disabling and enabling different parameters and observations
Describe the solution you'd like
A button in the GUI which shows what parameters and observations are loaded, and the option to disable a subset for the update step. This should also be possible to do in the config though for example a new keyword (UPDATE_CONFIGURATION?)
Describe alternatives you've considered
This is already partially implemented through the update_configuration property on EnKFMain, so it should not be very complex to resolve.
