--sequence means write JSON text sequences.

Instead of standard GeoJSON feature collections.

--with-rs means add RS delimiters, making output conform to https://tools.ietf.org/html/draft-ietf-json-text-sequence-11.

Also, some parameter consolidation into a new params module.
Please consider adding a little more to this message.
