Recipe with SpectralWorkbench interface running locally

We can source from spectral-workbench.js for the front-end, but I believe the capture interface on https://spectralworkbench.org/capture would need to be extracted into its own repository and modified. Which is probably for the best anyways!

This would be nice for running the spectrometer off a Raspberry Pi instead of a webcam!

Opening at #73 ! It won't work until publiclab/spectral-workbench.js#103 is merged and #73 is rebuilt.
