ad3be1f4c7 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.

490b92b1fd 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

883b712a53 gateware: fixed various bus issues
- 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

1cfa5a47de 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.
