Implement GOFF-GRATCH FORMULATIONS for water vapour #2
Tetens and Magnus formulations are simpler but Goff-Gratch may be preferred under some conditions.
Implemented in version 0.9.25 for saturation water VP, inverse not yet implemented. Need to find the inverse equation formulation or derive it.
Added forward and inverse implementations of Wexler. See http://www.decatur.de/javascript/dew/resources/its90formulas.pdf. ITS90 of forward equation needs the replacement of constants. Currently forward follows ITS68 as the original formulation, while the only inverse available follows ITS90.
