Non-adaptive localisation fails when using FIELD in ERT config and there are no specified keyword for field_scale for the same correlation group

[oddvarlia]

Describe the bug
The non-adaptive localisation implemented in the job LOCALISATION_JOB in semeio fails if the ERT model contains fields and localisation config specify correlation group containing the field parameter but without specifying field_scale keyword in the localisation config. What happens now is that missing specification of row_scaling input for this case makes localisation fail.

To Reproduce
Run the localisation job using a correlation group which uses a field parameter in the parameter group and where no specification of scaling was specified (e.g. missing the keyword field_scale in the localisation config file for that correlation group.

Expected behavior
The localisation should work also in this case, but with scaling factor equal to 1 for the fields in the correlation group. This means that original estimated correlations between the field parameter values and the observations in the correlation group should be kept unmodified. What A clear and concise description of what you expected to happen.

The purpose was to run with field without having to use any method to modify the correlation by distance or region. By introducing a method constant we can achieve this with default scaling = 1.
