Add legacy mode for third parties flashrom avrdude

[therealdreg]

Bus Pirate v5* & v6-> (flashrom, avrdude & asprogrammer dreg mod, from #81 )

The idea here is to create something small and simple that works with third parties, not to implement everything. So the code I've written is a bit tricky (for example, I’m telling flashrom that I’m a Bus Pirate v2.5 (HW) so that it keeps the UART baud rate at 115200 by default...)

Just tested it with flashrom on some random chip and it worked.

Only thing that is missing pin labels on the LCD after entering the mode and maybe a way to get out of the legacy binmode without disconnecting and connecting.

@DangerousPrototypes can you run the workflow again plz?

[therealdreg]

For me, it’s okay to merge. I’ll start making much smaller and more manageable PRs to gradually improve things. @DangerousPrototypes

I’ve compiled it manually on Windows, and it works. From looking at the workflows on macOS and Ubuntu, it compiles there as well, so everything is good.
