PDAL doesn't support this, but you can chain writers to get separate
rasters. I assume GDAL has some VRT magic to merge the separate tiffs into
a multi-band:

[
    "/pdal/test/data/las/autzen_trim.las",
    {
        "type":"writers.gdal",
        "dimension": "Red",
        "filename": "red.tif",
        "output_type": "idw",
        "resolution": 100
    },
    {
        "type":"writers.gdal",
        "dimension": "Green",
        "filename": "green.tif",
        "output_type": "idw",
        "resolution": 100
    }
]
