External block wrapper support added in cumulus/plugins.macro.
* New: In cumulus/plugins.macro.macro.Macro() to encapsulate foreign blocks.
Round their size to an exact number of GCells and a guard of one GCell.
External terminal must be on the periphery and will be made to stick out
in the guard ring. This is sub-optimal for now but provide a workaround
some Katana bad assumptions.
A "perpandicular padding" is also added to terminals to limit the
offgrid related problems. Have to optimize that in conjuction with
Katana.

The abutment box of the block is enlarged so both it's dimensions

are a multiple of the sliceHeight. It is then enlarged of one more

sliceHeight on each side. The resulting block will:

* Exactly fit the GCell grid.

* Eternal pins will be isolated in fully empty GCells on the side.

Due to some quirks in the P&R algorithm, putting them in GCells
|

that are half free and half occluded by the block itself may

cause (stupid) deadlock to appear.
