Merge branch 'fix/HistoryPts3DH1D' into 'master'
FilterHistoryPoints with 3DH1D This MR changes how `FilterHistoryPoints` works in 3DH1D: - The points are not required to be all in the same plane any more. When `OutputPlane` is not defined, each point is positioned in one of the planes closest to its z-coordinate. Using `OutputPlane` still forces all points to be in that plane. - By default, the output is now in physical space (this effectively replaces !516). Writing the result in wavespace is still possible using the new option `WaveSpace`. See merge request !621
