9bfd8c1cf5 TL2 WidthWidget (#258) 
* tilelink2 Narrower: support widenening and narrowing on all channels

Be extra careful with the mask transformations

We need to make sure that narrowing or widening do not cause a loss
of information about the operation. The addr_hi+(mask|addr_lo) conversions
are now 1-1, except on D, which should not matter.

* tilelink2 SRAM: work around firrtl SeqMem bug

* tilelink2 WidthWidget: renamed from Narrower (it now converts both ways)

* tilelink2 mask: fix an issue with width=1 data buses

d2421654c4 tilelink2: refactor address into addr_hi on ABC and addr_lo on CD 
We need addr_lo in order to properly convert widths.
As part of the refactoring, move all methods out of the Bundles
