LoHalo resampler simplification

I unfortunately don't have time to do it myself even though it is an easy job, but could someone rip out the internal conversions into and out of "sigmoidal color space" and just use whatever is incoming (linear float light, if I remember right) both for the EWA Robidoux component (already uses linear light) and the tensor Mitchell-Netravali component (converts inputs by passing them through a sigmoid, convolves, undoes the sigmoid)? If things look weird after this change, just keep an eye for constant folding. I don't remember doing any that affects the above change, but I've not looked at this code for a while.
