Uses

- yaeos__math_continuation
- stdlib_optval

Saturation pressure calculation function.

Calculates the saturation pressure of a multicomponent mixture with a given molar composition n. It is possible to calculate:

Bubble point: kind="bubble"
Dew point: kind="dew"
Liquid-Liquid point: kind="liquid-liquid"
