Implement handling for AffineTransform edge cases

[Oliver-Loeffler]

• multiple displacements along a straight line in either X or Y direction
• multiple displacements at a single point

These cases usually end up with singular matrix exceptions or errors but basically a handling is possible.

Ideally this condition is detected before an exception occurs, so that the error handler in AffineTransformCalculation can be eliminated later on.

[Oliver-Loeffler]

Multiple displacements along a straight line in either X or Y direction are now handled by net.raumzeitfalle.registration.distortions.JamaOneDimensionalAffineModel which still uses the JAMA QR decomposition and the AffineModelEquation but parameterizes the matrices differently. Thus there is no runtime exception with "Matrix is singular" message anymore.

Still missing, handling multiple displacements at a single point.

Also still missing, a good way to perform the actions without so many ifs and elses.
