a little bit hacky, as we are just sending commands to the BP and then dropping into bridge mode on the same uart.

Requires user to press the BP button during the flash

@kiram9 I wonder, does this work without any previous preparation on the BusPirate's console?
I feel like we have to be in uart mode already, we have to have power via W enabled, and pullups via P enabled?

I think that's not necessary if VOUT/VREF is connected so the buspirate knows the reference voltage instead of us having to set it to 3.3V.

Did I ever try this? I think not. The buspirate does not have pulldowns, only pullups.
