Add fprops_Tvsh_ph to asc_helmholtz for calculation in terms of (p,h). The
routine does not seem to work particularly well though.

Seem to have fixed the solve_ph problems, but new problems in fprops_sat_p have arisen.

Improved first guess has eliminated many of the errors, still problems though.

Adding better starting guess for T,rho when solving (p,h) in compressed subcritical liquid region.

Diff to previous 2260
The (p,h) function is converging almost everywhere. The home-made Newton iteration wasn't starting well for supercritical states
when the starting guess had rho = rho_c, so changing slightly away from fixed almost all the problems.

Working on convergence of (p,h) over wide range.
