Allow for tolerance comparison of BSpline domain origin
Allow for tolerance comparison of BSpline domain origin

In ITKv5 with the commit 794c82d16ebc4b4035f37e0675176e7677f9bd68, the
consistency of the parameters has been fix but there is a little
variability with some of the transform domain values derived from the
parameters. This patch adds tolerance to certain test of derived
transform domain values as needed.
