[pdal] how to change the data type of an attribute(or field) when exporting the las file

[Andrew Bell]

Unless you use extra bytes, the LAS format does not support this, as the
data types are fixed.

If you use extra bytes, you can use the 'extra_dims' option to choose the
type of the output dimension.

You should read the LAS specification for details.
