[NOBUGS] Mantid Imaging 2.3 release

[Sam Tygier - STFC UKRI]

Mantid Imaging 2.3 has been released on 25 Feb 2022. Mantid Imaging is a graphical toolkit for processing neutron imaging and tomography data written in Python 3. It provides an easy-to-use graphical interface to a wide range of pre/post-processing operations, tilt correction and reconstruction algorithms, accommodating for tomography users with varying data complexity and image analysis background knowledge. It utilises a flexible plugin system that allows easy integration of external software and has allowed us to re-use software widely known in the neutron tomography community.

This release brings some significant new features:

Bad data indicators
    Show pixel values that can cause issues during reconstruction, NaNs (not a number) caused by missing data or invalid maths operations and non-positive values caused by noise or issues with dark frame subtraction.

Beam hardening correction
    Mantid Imaging now implements a linearization correction to compensate for the beam hardening effect.

Dataset side-bar
    The main window now shows a tree-view of loaded datasets and their stacks. Internally Mantid Imaging now has a more structured view of the loaded data, which will allow further user interface improvements.

User interface improvements
    The parameter controls in operations and reconstruction windows now have finer step sizes and better defaults. Auto preview in the reconstruction window can be disabled.
