This should be a user option, e.g. https://github.com/CERN/TIGRE/blob/master/Python/tigre/algorithms/krylov_subspace_algorithms.py#L66 or https://github.com/CERN/TIGRE/blob/master/MATLAB/Algorithms/CGLS.m#L94 We should have them on by default, but allow the user to disable it.

The code runs but there is some mistake in the algorithm that makes it numerically go bad.

PR #396 will introduce many algorithms, but among others in MATLAB a feature to compare to ground truth data. I personally simply don't have time to add the feature in...

Some algorithms don't return the residual norm, which makes them arbitrarily inconsistent. Make all algorithms return this. I assume MLEM would need to return KL divergence instead.
