Using Thermosteam and CoolProp in the same environment leads to errors

[nkawerau]

Describe the bug
Running a Thermosteam code in an environment with a clean thermosteam installation (pip install thermosteam) works fine. As soon as I install CoolProp (pip install coolprop) running the same code raises errors.

To Reproduce

import thermosteam as tmo

"""stream definition"""
H2O = tmo.Chemical("H2O")

chemicals = tmo.CompiledChemicals([H2O])
mixture = tmo.Mixture.from_chemicals(chemicals)
thermo = tmo.Thermo(chemicals, mixture, cache=False)

tmo.settings.set_thermo(thermo)

stream = tmo.MultiStream(ID="stream", l=[("H2O", 1)], units="m3/hr")

stream.set_property("T", 20, "degC")
stream.set_property("P", 1, "bar")

viscosity_H2O = stream.mu

print("thermosteam viscosity of H2O:", viscosity_H2O)

Expected behavior
thermosteam viscosity of H2O: 0.0010216146329967753

I do not expect the CoolProp installation to affect code execution.

** Actual behavior**

Thanks so much for submitting this issue, it should work with the latest version in PyPI (0.27.19) or with the master branch.
