`affmat2cmtkparams(matrix, centre = c(0, 0, 0))`

- matrix
4x4 homogeneous affine matrix

- centre
Rotation centre

5x3 matrix of CMTK registration parameters with a version attribute

The version attribute of the resultant matrix marks this as compliant with CMTK>v2.4 (~ Dec 2013) when a bug in affine matrix (de)composition was fixed.
