Fogpy fls_day should exclude pixels that aren't daytime #80

Currently fogpy will (I think) happily process nighttime pixels even if they are taken daytime, reporting them as being removed by various filters (presumably). It needs to explicitly filter out pixels that it can't process to begin with, to get better statistics of which pixels are removed for the right reasons.
