Upgrade to MSL 4.0.0 about externalmedia

[bilderbuchi]

Just to clarify, I was mainly present because of/interested in OpenModelica compatibility; luckily I am not encumbered by many pre-existing libraries/models. :-)

I did a quick test on converting the library (master branch) to MSL 4.0.0 with Dymola 2022.

• several incompatible units in test models (time is multiplied e.g. with a pressure to have a varying input)
  -in ExternalMedia.Media.BaseClasses.ExternalTwoPhaseMedium FluidConstants is replaceable, in MSL Media 2 phase mediums use an externally defined record for the fluid constants

Not simulating:

• ExternalMedia.Test.CoolProp.CO2.TestStatesSatSubcritical "T is not a valid number"
• ExternalMedia.Test.CoolProp.Pentane_hs "Inputs in Brent [143.470000,578.730000] do not bracket the root. Function values are [6916.155129,60536.779546]
  The stack of functions is:
  setState_hs_Unique29
  setState_hs_Unique29(h, 1500.0, 0)" (last model I tested today)

Just a comment for Dymola: One has to set Advanced.RelyOnCompiledFunctions=true; in order to prevent Dymola from trying to recompile the external functions (Default behaviour up to Dymola 2018, has been changed after that). See Chapter 5.5.9 in the manual
