Iterative-ensemble-smoother

What's Changed

The main change is the reduction of memory usage of the ensemble smoother and added support for full observation error matrix.
Only changes that might be of interest to users are included in the following list.

* Add option to turn on / off projection by dafeda in https://github.com/equinor/iterative_ensemble_smoother/pull/43
Projection of response matrix, aka the "A^+A projection" is needed when the number of parameters of the full global state vector is less than or equal to the (number of realizations - 1).
The projection is not necessary when for example updating a subset of parameters separately, even when the subset contains less parameters than (number of realizations - 1).
Hence the need to be able to turn off the projection.
