Issue with using 2D images in tigre.utilities.im_3d_denoise

@AnderBiguri That works! ```python ##2d image example - 1 slices from tigre.utilities.im_3d_denoise import im3ddenoise from cil.utilities import dataexample import numpy as np from tigre.utilities.gpu import GpuIds, getGpuIds, getGpuNames from cil.utilities.display...

Geometry utilities cast to single, casts integers to single too

Thanks Ander - We have it in CIL and can't remember why we use it either :)

docker build fail

Seems to be passing this morning (although slowly) https://github.com/TomographicImaging/CIL/actions/runs/15047473746/job/42345710795?pr=2158

ISTA/FISTA step_size property could unintendedly increment the step size

In GD we just chicken out if it isn't a constant step-size: https://github.com/TomographicImaging/CIL/blob/3230c7599ab40839098d1deebbd5c444f67f7d69/Wrappers/Python/cil/optimisation/algorithms/GD.py#L138-L144 We should probably be consistent

Gradient operator - allow anisotropic scaling

Discussed in the dev meeting this morning. To get around the question of it should scale like an Operator or like a BlockOperator could be avoided if we added a...

Added LSQR algorithm

Closes #1992

Added LSQR algorithm

Thanks Maike! Will take a look

Added LSQR algorithm

I had a play with this to try and optimise memory usage. Compared to CGLS, I still need to get rid of one stored image copy. Will discuss with Gemma...
