Support displacement vector origin in transformations

[paulromano]

On TR cards and TRCL keywords, MCNP allows a 13th parameter m called the displacement vector origin that determines whether the displacement vector specifies the origin of the auxiliary coordinate system defined in the coordinates of the main coordinate system (m=1) or vice versa (m=-1). This PR adds support for this parameter. In the case that m=-1, it simply negates the displacement vector.
