Purpose

To emit fibonacci numbers on io_out[37:8] on every clock (configurable). This being 30-bit wide it effectively limits it to 44 iterations, so after that it restarts from the start after that. There is also WishBone operations to send and receive data.

This is part of the zerotoasic multi project submission to fit within a 300um x 300um area.
