New sigma turbulence model not included for compressible LES

Summary

The new 'sigma' turbulence model introduced in v2206 for LES is not applicable for compressible simulations, but only for incompressible simulations. Maybe it was forgotten to be implemented in commit 54806ea7 , as the file /src/TurbulenceModels/incompressible/turbulentTransportModels/turbulentTransportModels.C was altered but not /src/TurbulenceModels/compressible/turbulentFluidThermoModels/turbulentFluidThermoModels.C.

Possible fixes

Add the following lines to line 134 of the file /src/TurbulenceModels/compressible/turbulentFluidThermoModels/turbulentFluidThermoModels.C:

#include "sigma.H"
makeLESModel(sigma);
