AffineTransform should not center data upfront

[Oliver-Loeffler]

The AffineTransformCalculation function centers the given data before doing any calculations. There are cases, where this centering is not wanted. To cover those cases, try following approach:

• remove the centering code from AffineTransformCalculation and instead compose it with a variant of net.raumzeitfalle.registration.alignment.TranslateToCenter.
• A new version of TranslateToCenter is needed, as the center calculation should be controlled by a Predicate<Displacement>.

[Oliver-Loeffler]

The translation step is not yet controlled by a predicate but moved into a separate function.
