SU2 version 7.2.0 "Blackbird"

SU2 version 7.2.0 introduces exciting new features and improvements (it differs from 7.1.1 by almost 1000 commits!)
We made a pause from the monthly maintenance-release cycle to integrate those features as best as possible, they include:

• Unsteady discrete adjoints for multizone problems (e.g. FSI and CHT).
• Hybrid parallelization (MPI + OpenMP) of discrete adjoint solvers.
• New boundary conditions and important corrections to RANS wall functions and transition models.
• Usability improvements, such as speeding up the NEMO preprocessing for large problems, restarting from results on non-matching grids, suggestions for incorrect config options, etc.
• Numerous fixes based on feedback from the SU2 community.

As with 7.1.0, we used this version to deprecate some more options leftover from 7.0.0, and to revise others in preparation for new features to come.
