[pdal] read scalar field as intensity in reader.ply

[Andrew Bell]

You can't do this directly with a command-line option, but there are
alternatives:

1) The header of a PLY file is ASCII text.  You can simply change the name
of the field that's called "gray" (or whatever) to "Intensity".
2) You can add a ferry filter after the ply reader in your pipeline to copy
the data from the gray field to the Intensity field.  If you're using "pdal
translate", you can add the ferry filter to the process by using `-f ferry
--filters.ferry.dimensions "gray=>Intensity"
