gateware: put in some testing infrastructure
...
It's pretty hacky tbh, probably should be improved.
But also this will probably scale with the entire project so I don't
care.

gateware: first work with I2C peripheral
...
Basic details seem to be working, and I'm on my way with testing.
Next steps:
- Build out more local testing utilities
- Build out unittest infrastructure
- Flesh out more tests to verify operation

- The Record.connect() function returns statements that need to be added
to the comb domain.
- Addressing of the devices works on word-sized chunks, so everything
needs to be adjusted there

firmware: made some rust firmware to test
...
Had some issues due to lack of startup code (stack pointer was unset,
leading to underflow in address space), so decided to just get the rust
FW started instead of finding some startup code to use.
