Improved MoistAir.T_phX:
This function computes T by inverting function h_pTX. The temperature range of the inversion
was previously set to 200 ... 6000 K. This was changed to 240 .. 400 K.
Since the range is much smaller, the numeric solution of the scalar non-linear equation
system will be faster.
