Implement guesses based on Temperature or Quality
Users should be able to specify a temperature or a quality guess, and based on this together with the pressure guess at the same point, the starting value of enthalpy can be calculated.
To provide further context:
It is already possible to provide guess values to give the tespy solver a starting point. However, the guesses are only used for the variable in question, for example, h0 is a guess for the enthalpy and x0 is a guess for the vapour quality, but they are currently only used for the enthalpy and vapour quality respectively.
However, these guesses could also be combined with other variables or variable guesses. For example, if x and T0 or x0 and T0 have been defined it is possible to also calculate p0 and h0.
Currently, this has to be done externally, e.g. using CoolProp to calculate the enthalpy and pressure and then provide these as guesses to the solver.
