Error estimation method need to be updated for high count rate cases #16

Currently, errors are estimated assuming Poisson statistics. However, if there is significant saturation, the errors could be underestimated. See

N. P. M. Kuin, S. R. Rosen, The measurement errors in the Swift-UVOT and XMM-OM, Monthly Notices of the Royal Astronomical Society, Volume 383, Issue 1, 1 January 2008, Pages 383–386, https://doi.org/10.1111/j.1365-2966.2007.12549.x

I think the application of saturation correction fixes this problem. I am closing this issue.
