🦟 Bug fix
Depends on #2770
Summary
The mesh inertia calculator can potentially generate invalid inertial values for complex / non-water tight meshes. This PR adds a function that attempts to correct the auto-calculated mass matrix if it is strictly positive and within the specified tolerance of satisfying the triangle inequality.
Credits go to @shameekganguly and @scpeters for the mass matrix correction algorithm
