Self-adjoint / Hermitian eigensolver

Thank you for your work!

I would like to compute an eigendecomposition of (low dimensional) Hermitian matrices of complex numbers (equal to its conjugate transpose).

The [user guide](https://nalgebra.org/docs/user_guide/decompositions_and_lapack/) gave me the impression that this was implemented in nalgebra. Yet, in the API documentation I could only find SymmetricEigen, which seems to require symmetric matrices (equal to its transpose).

Am I misreading something? Do you plan to implement an algorithm for Hermitian matrices, too? It would be extremely nice to have, as most matrices in quantum mechanics are Hermitian.
