* As a consequence, made update function take CoolProp::input_pairs enum as first input (thanks @jowr for the idea)
* Decoupled the pre_update and post_update functions in order to allow for more creative update functions using guess values, etc.

Should in the end only slow down by 1.2x, but calculate at least up to second order derivatives all at once, so net speedup of 5 if calculating all first and second order partials !!
