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

For FreePDK45 word_size=8, num_words=256

Improved
*** Maze routing supplies: 89.8 seconds
** Routing: 279.3 seconds

Non-improved
*** Maze routing supplies: 105.1 seconds
** Routing: 293.5 seconds

Bastian Koppelmann 7ff5121d8c base/pin_layout: Implement hash cache 
the hash value only depends of the properties 'rect' and 'layer' so we
only compute the hash if those values are changed. Otherwise we just
return the precomputed value. This gives us a major speedup (~10x) if
the hash is used as a key in a dict.

During the grouping of pins in analyze_pins() this gives the best
improvements. For example for FreePDK45 with num_bits=8, num_words=256

Improved
**** Analyzing pins: 20.9 seconds
** Routing: 293.8 seconds
** SRAM creation: 349.8 seconds

Non-improved
**** Analyzing pins: 267.9 seconds
** Routing: 537.5 seconds
