SU2 version 7.3.0 "Blackbird"

[pcarruscag]

SU2 version 7.3.0 introduces important new features:

• Passive species transport (tutorial).
• A smoothing method for discrete adjoint gradients (example).
• Customizable objective function (example).
• Options to keep intermediate solution files (documentation).
• Robustness improvements of the NEMO solver.
• HDF5 backend for CGNS meshes.

This release includes an important fix to the SA-neg turbulence model which could reduce oscillations in the solution, the option CONV_CRITERIA had been marked for deprecation in v7.2.1 and it is now removed.
