Added testbench for checking that the housekeeping SPI is accessible when
...
the user area is powered down. Because this requires some changes to the
padframe definition, this testbench currently fails.

Renamed the poorly and awkwardly named "sky130_fd_sc_hvl__lsbufhv2lv_1_wrapped"
...
cell to the simpler (and easier to remember) "xres_buf".

Implemented a system for setting the GPIO power-on defaults through
...
via programming. The values for each of the GPIOs at power-up are
defined in the "user_defines.v" file. For the verilog, they are
applied as parameters. For the layout, they will need to be
separately defined cells for each of the GPIOs, or at least for
each set of unique default values.

First major update; current code passes syntax checks in iverilog
...
and simulates, but fails testbench (not surprising at this stage).

Seeding with documentation of pinout and verilog RTL (mostly unchanged
...
from original except to remove blocks that are not supposed to be in
this repository like the processor core and the storage).
