SHR3D is available as writers.shr3d and can be appended to any PDAL pipeline.
PDAL will not be altered to infer writers.shr3d (many writers could write a
TIF), so users will have to specify writers.shr3d explicitly.
ALIGN3D is available as filters.align3d and can be inserted into any PDAL
pipeline. ALIGN3D will take the first incoming PointView as the fixed or
reference PointView, and will register all subsequent PointViews to this
reference view.
Minor changes: Ignore build directory for in-source builds. Add clang-format
config file (the plugin code adheres to this).
PubGeo common code updated to read directly from PDAL PointViews. Common code
also updated to silence a bunch of warnings.
