### Description

Extract retrieval error from covariance matrices.
Extracts the error estimates for the retrieved quantities from the covariance
matrices for the error due to measurement noise covmat_so and the error due
to limited resolution of the observation system covmat_ss and stores them in
the vectors retrieval_eo and retrieval_ss, respectively.
To etract these errors, first the convariance matrices of which the errors
should be extracted have to be computed using the WSMs covmat_soCalc
and covmat_ssCalc or set to be empty in order to be ignored. Note, however,
that this will also set the corresponding error vector to be empty.
