Project: The cpu finally works perfectly now even at full speed as far as i can tell! I made the ram and register writes synchronous which fixed the weird issues I had, then I added -abc9 to yosys so that nextpnr can actually route the cpu at full speed and increased the display fifo since the cpu is so fast now!!

Peripherals/HD44780: Rewrote and cleaned up a lot of the driver code. Unfortunately what i think is a very weird bug in yosys is still affecting the codebase

Added simple support for \n and \r on the HD44780 driver, increased the synthesised mem to fit brainfuck_compiled.asm and made it the default.

Added an I2C driver, a PCF8574 driver and an HD44780 display driver. Unfortunately this shows that even fibonacci doesn't run correctly. Nonetheless, I made colored_led.asm output text to the display!
