COMP: Numerical computation precision limit in resampling

Coordinate computations for nearest neighbor are computed at the limits of numerical precision for this image during resampling. arm64 and x86_64 compute input continuous index coordinates as 105.39999999999999 vs 105.4 which requires a slight tolerance acceptance in the comparisons Add --compareRadiusTolerance 1 to test validation.
