NOAA 64 and 127 levels are no longer correct

[bena-nasa]

I was asked to regrid some of our emissions to the 64 and 127 levels used by NOAA and UFS for the gocart collaboration. I was given what I'm told is their current 64 and 127 level ak and bk's. I noticed that what I was given slightly different (like in the 2nd or 3rd decimal place) than what is currently in m_set_eta. Should our m_set_eta be updated to reflect this.

Note also that a while back, I remapped emissions to L127. I don't think anyone is using them (🤷🏼‍♂️ ), but if so, we'd probably need to rename/deprecate those if we update the 127 ak/bk.

@bena-nasa I would imagine we would want to update m_set_eta to reflect what NOAA and UFS actually use. At least for consistency. However, the implications of this are probably better realized by @rtodling and @wmputman
