Subject: [PATCH] [VnV][telemac3d] Update vasque example with better choices
for 2 keywords - use of gradient conjugate + preconditioning 34 = 2*17 to
solve PPE, more efficient than GMRES or CGSTAB (previous choice) for this
example

The non-hydrostatic version of \telemac{3D} is used.
To solve the advection, the method of characteristics (scheme \#1) is used for
velocities.

+The conjugate gradient (option 1) combined with preconditioning = 34
+= 2 $\times$ 17 is used for solving PPE as more efficient than GMRES (option 7)
+or the former choice CGSTAB (option 6) for this example.

The time step is 0.5~s for a simulated period of 300~s.
