865 gds handle multiplanar design with multiple chip names and layer. (…

…#869)

* Fix typos, add method for getting chip size to multi-planar

* Fix linting and typos

* Add logic to allow for junctions to be in multiple chips.  Thus, a file with junctions only needs to be imported the gdspy only once.
