Add a `pdal` plugin relying on vtkPDALReader

[Meakk]

Context F3D is great to visualize point-cloud but supports a limited number of file formats.
VTK has a PDAL wrapper that could be integrated easily in F3D as long as the VTK IOPDAL module can be easily built.

PDAL supported file formats: https://pdal.io/stages/readers.html#readers VTK IOPDAL module: https://gitlab.kitware.com/vtk/vtk/-/tree/master/IO/PDAL

Suggested solution

• Add a new pdal plugin that relies on the vtkPDALReader.
• Add CI logic to test the new plugin (optional)
• Add PDAL to the f3d-superbuild (optional)

Notes

• See the vdb plugin for inspiration, it should be pretty similar

@Meakk @mwestphal I'd like to work on this issue. Could you please assign it to me?

[Meakk]

Sure go ahead. Note that this one should be more challenging, but feel free to reach out on discord if you need pointers.
