[argyllcms] Feature request (and an implied question)

spotread -a -v already shows ambient light levels in lux. Would it be possible
to also show light levels in EV units?
The conversion (for ISO 100) is:
EV = log2(lux / 2.5)
lux = 2.5 * 2**EV
The implied question, of course, is, ``Does it make sense to calibrate a
lightmeter by making it match the measurements made by Argyll with an i1 Pro in
ambient mode?'' I can't imagine why not, but....
Cheers,
b&
