Fix some issues related to the Courant number
...
step_h was using the wrong timestep; fixing it caused update issues
based on the Courant number being 1.0, i.e. too large. Reducing it to
\sqrt{3}/3 fixes stability issues. Unfortunately, a non-Unity Courant
value prevents me from using the ideal Absorbing Boundary Condition I
had just implemented, so that's been disabled.

Factor out a Neighbors to package up all 6 neighbors when updating cells
...
This will allow more flexibility in boundary conditions.
It seems to have similar perf as passing only the 3 cells within about 2%.

step_e now makes the boundary condition explicit as well
...
This paves the way for implementing a single 2d plane within a 3d
simulation.
Unfortunately it increases the reflections, however this could be made
to accept explicit BoundaryCondition parameters to explicitly nullify
reflections instead.

step_h uses optional left/down nodes.
...
This will be handy for implementing 3d, because the world with depth=1
(i.e. no neighboring xy planes) will behave the same as a 2d simulation.
