3ff6205e93 Add weak pull up (NEED STRONGER PULLUP)
weak pullup is enabled, but these are only about 40k when 10k is needed.
I added two 10k resistors to the board.

b8161e3082 Add LED module and address decoding; disable LA
The Logic analyzer isn't that useful anyway since it does not track
rising and falling edges.

fcae23785e Throw everything up
I think that previously, I had not actually commited any of this to git.
This adds all of the new effinix stuff that I had been working on for
months.

The gist of all of this is that the intel fpga is expensive and does not
exist, whereas the effinix ones are not as expensive and more existant.
This redoes the project to use the dev board, as well as a custom board
that I may or may not make.
