Note Regarding Infra-Red Range

The T5 Ruleset inadvertently made an error in the assignment of nanometer wavelengths to the Infra-Red Ranges on the Sight Sense Table. Apparently, someone mistook 1000nm for 1000μm, and the "Far Infra-Red" Range downward is off by a factor of 1000 or more. I have made an attempt at a suggested errata-corrected table below for those interested in correct values.
