Description
In issue #119, we had occasional negative values of radiance, that were resulting from negative emissivity values for VIS/near-IR channels. CRTM attempts to compute emissivity for all channels, regardless of whether they'd produce any thermal radiance or not. This PR is fairly heavy-handed in bounding surface emissivities and reflectivities to be between 0 and 1. The risk is that this could potentially mask other emissivity problems.
Please test for VIS/near IR channels in particular, GOES ABI channels 5-7.
If emissivity/reflectivity/direct_reflectivity tries to be less than 0 or greater than 1, it is set to either 0 or 1, respectively.
