1512 rand_gaussian_noised with multiple keys

[rijobro]

Fixes #1512.

Description

Create a list of noise realisations, with length equal to the number of keys. The noise realisations can all use the same mean, or a mean can be specified for each of the keys. The unit test has been updated to run for multiple labels.
