Optimised compute_fluxes by disabling limitation of momentum perpendicular to the x-axis. Speeds calculated from the x-momentum are still being limited according to the _compute_speeds. All tests pass and the overall improvement is as follows:
For the simple profile compute_fluxes improved from 4.284s to 3.372s and the overall runtime of evolve from 10.909s to 9.941s. This is an overall speedup of more than 8%.

For the okushiri profile example the improvement of compute_fluxes is from 129.432s to 111.703s and the overall runtime was reduced from 312.336s to 293.286s or about 6% improvement. This is probably the more realistic profile.
