API change and pinhole camera distortion tools

Major release

In addition to the API change in the ff-HEDM config object and associated η-ω maps, the PowderCalibrator class can now accept an xrdutil.phutil.SampleLayerDistortion class to apply the 2θ distortion associated with an offset sample layer in a pinhole camera instrument (e.g., TARDIS, PXRDIP). The corresponding class for actual pinhole lines themselves is not yet implemented (staged, using functions from @ryanrygg). Below is a simulated TARDIS image with the cyan and orange overlays coming from 5μm thick layers at 150μm and 250μm offsets, respectively; the aforementioned distortion caused the nominal 2θ values to appear curved (note the simulation captures the distortion effect on account of being voxelated, while the correction follows @ryanrygg's Eq 10 from the TARDIS paper.

As for the ff-HEDM config API, now the hkls used for constructing the η-ω maps are specified by the explicit list of (h, k, l) indices (any symmetric equivalent) or the list of global G-vector ids from the material (less preferred). This removes the ambiguity associated with the previous convention of using indices into the reduced hkl list. For example,:

find_orientations:
  orientation_maps:
    # A file name must be specified. If it doesn't exist, one will be created
    file: null

    threshold: 250 # threshold on raw images to build maps
    bin_frames: 1 # how many successive frames to bin. default is 1

    # specify which hkls to use
    # "all", or a list of hkl indices.  Note that the default value of "all"
    # means all hkls that are not marked as excluded in the material definition.
    # can be a list of indices or a list of [h, k, l].
    # !!! used to be active_hkls: [0,1,2,3,4,5]
    # !!! this was really [0,1,2,4,6,7] considering the material parameters above
    active_hkls:
      - [0, 1, 2]
      - [1, 0, 4]
      - [1, 1, 0]
      - [1, 1, 3]
      - [0, 2, 4]
      - [1, 1, 6]
