NMODL translated MOD files get unit constants typically from share/lib/nrnunits.lib.
But there were other source files that hardcode some of the constants. Here we gather a few modern units into a single place (but, unfortunately, also in nrnunits.lib).
These come from https://physics.nist.gov/cuu/Constants/index.html. Termed the "2018 CODATA recommended values", they became available on 20 May 2019 and replace the 2014 CODATA set.
