filters.python produces broken metadata when 2 or more files processed #87
Description
When running pdal pipeline with filters.python inside and requesting metadata output is broken by unquoted string values.
Example pipeline:
[
{
"type": "readers.las",
"filename": "1.2-with-color.las"
},
{
"type": "readers.las",
"filename": "1.2-with-color.las"
},
{
"type": "filters.python",
"source": "def foo(ins, outs):\n return True",
"module": "anything",
"function": "foo"
},
{
"type": "writers.las",
"filename": "/tmp/out.laz"
}
]
Run:
pdal -v 8 pipeline --metadata m.json pl.json
