Bastian Koppelmann 76256a2f1b sense_amp: Allow custom pin names 
we don't want to propagate the sense amp's bl/br names out of the
sense_amp_array. Thus the sense_amp_array gets them named as
"bl"/"br" again.

Bastian Koppelmann 9749c522d1 tech: Make power_grid configurable 
this is the first step to allow engineers, porting technologies, more room
for routing their handmade cells.

For now, we don't allow the specification of power_grids where the lower layer
prefers to be routed vertically. This is due to the router not
connecting some pins properly in that case.

Bastian Koppelmann 988df8ebb9 hierarchy_layout: Add methods to create via stacks 
this allows us to simplify add_power_pin() and gives a clean
API to create vias through multiple layers.

Bastian Koppelmann c0c89e465a vector: Implement hash cache for vector3d and vector 
this gives us a small runtime improvement in the router.
