Title: Exposed LAPACK's TRSYL Sylvester Equation solver, including test.

This change exposes LAPACK's Sylvester equation solver, which is common in controls engineering and becomes useful when solving related equations such as the Lyapunov or Riccati equations. A test was included to ensure the exposed LAPACK routine is working properly.
