I'd flip these around so
in_intensity_uvc_wavelength_max etc
Fits better with existing forms in the ABI (I think) and also will
list them in a more useful order when the directory is sorted by name.
Otherwise, I'd like to let this sit for others who work with light
sensors to comment as ideally we'd extend this to visible wavelengths
as well.

We have carefully killed off wild cards in the actual What lines as they make
automated parsing of these files tricky. So just list both options out longhand..
