Major changes

The proper ancient feature computation code running in the background of MIRP has been completely refactored. We
moved from a functional backend where all features were computed per feature family to a more flexible
object-oriented approach. Although this change is not visible at the user-end, it offers several new possibilities:
- Single features can now be computed. In addition, for some features (e.g. percentile statistics), a flexible
  percentile value could be passed.
- Creation of feature maps.
- Output of features and their metadata to machine-readable formats, instead of just tabular data.
Important: Though the name of features in the tabular exports has not changed, their ordering may have.
Avoid using column position when processing or analysing feature data.
Apparent diffusion coefficient (ADC) maps, diffusion contrast-enhanced (DCE) MRI and multi-frame DICOM objects in
general are now supported.
Planar imaging, i.e. computed radiography, digital X-ray and digital mammography DICOM files are now supported.
Python version 3.12 is now supported thanks to recent updates by the maintainers of ray and itk.
This means that mirp now supports Python version 3.10 and later.
