Port remaining tools back into new Capture interface, next steps

[jywarren]

After https://github.com/publiclab/spectral-workbench.js/issues/219 and https://github.com/publiclab/spectral-workbench/issues/645 we have the new Capture system running in SpectralWorkbench.org, at https://spectralworkbench.org/capture/v2

This is awesome. Now let's get all the different tools we had before ported into the new interface. You can see a range of buttons on the left side of the old capture interface https://spectralworkbench.org/capture/:

We don't need the scripting or centroid ones, but the remainder are:

• [x] geocoding of your spectrum (i don't think this was working anymore in old capture) https://github.com/publiclab/spectral-workbench/pull/851
• [ ] detection of fluorescent lights (this then offers to calibrate, with an alert along the top!)

There's not all that much left. What else might we add?

• [ ] allow different horizontal pixel resolutions if camera allows (instead of just scaling everything to 640px wide) -- but probably limit to 1280 max for the time being due to speed concerns
• [ ] display of horizontal pixel resolution (which changes with different camera sizes)
• [ ] integrate auto-spectrum matching? https://github.com/publiclab/spectral-workbench/issues/66, or see "Find Similar" button on spectrum pages like https://spectralworkbench.org/spectrums/226540

And let's remember, we would need to get some of these working in spectral-workbench.js first, then move to the Rails app.
