Remove unused and unmaintained modules

[jcfr]

Thanks for updating these. We are indeed still using these regularly and though some are outdated and do not need to be maintained (from our end): 3D4DImageConversion, DTITensorNormalization, DWI_NIFTINRRDCONVERSION, ImageNoise, anything in Unsupported and one of the curve comparison (not sure which is right one of the 2). Thanks also for updating the dtiprocesstoolkit

The following modules should be removed and associated external project archived.

Ideally, the relevant README files should be updated to:

• include History section summarizing when each was functionality was added and by who
• which tools can be used to perform similar operation

List of modules to retire:

• 3D4DImageConversion
  • Integrated in CMakeLists.txt here. See also https://github.com/NIRALUser/3D4DImageConversion
• DTITensorNormalization
• DWI_NiftiNrrdConversion
• ImageNoise
  • Integrated in CMakeLists.txt here. See also https://github.com/NIRALUser/ImageNoise.git
• Unsupported/CorrespondenceEvaluator
• Unsupported/DMDBiomarkerTool
• Unsupported/IntensityRescaler
• Unsupported/TextureBiomarkerTool
• Unsupported/TransformDeformationField

@styner Did we properly capture the list of functionalities that could be retried ?

[styner]

Yes, these can be retired
