Consider removing "TransformBendingEnergyPenalty" from metrics returned by GetDefaultParameterMap

[N-Dekker]

ParameterObject::GetDefaultParameterMap("bspline") returns a parameter map whose "Metric" parameter has values { "AdvancedMattesMutualInformation", "TransformBendingEnergyPenalty" }:

Line 509 in 7c76da1

parameterMap["Metric"] = { "AdvancedMattesMutualInformation", "TransformBendingEnergyPenalty" };

On the other hand, for "translation", "rigid", "affine" and "spline", GetDefaultParameterMap(transformName) returns a map whose Metric is just "AdvancedMattesMutualInformation".

Marius (@mstaring) suggested to consider removing "TransformBendingEnergyPenalty" for bspline as well. "TransformBendingEnergyPenalty" may not be necessary. Moreover, it may make things easier for the napari plugin, when all its "non-custom presets" share the same Metric by default. (Related to issue SuperElastix/elastix-napari#58)

To be discussed.
