Be smarter about printing gas partial pressure text

Browse source 
We always want to print absolute maxima and minima - but not when multiple
consecutive data points all have the same value (this happens, for
example, when printing a pHe plot on non-helium dives - or when the dive
profile includes a brief surface intervall which causes all the partial
pressures to be at their minimum).
