Added the sky130_sram_macros library from the github/efabless
repository. These are used in the Caravel chip, but there is no
place where the underlying cells are made available in the PDK,
making it impossible to run LVS, DRC, or do simulation at anything
other than a black-box level of the whole SRAM block.
