SimplyPrint Duet3d integration

Many thanks to Tim Schneider at https://github.com/Meltingplot/duet-simplyprint-connector/ for originally creating this integration and allowing us to use it.

This package acts as a bridge between Duet-based 3D printers and the SimplyPrint.io cloud service.

It communicates with the printer using the Duet HTTP API. For more information, visit https://github.com/Duet3D/RepRapFirmware/wiki/HTTP-requests.

Communication with SimplyPrint.io is handled via the simplyprint-ws-client.
