Peripherals/Wishbone_memory: Rewrote the module to be more efficient, smaller and also support byte level addressing. It is correct enough now to run code out of!

ascii_to_HD44780_driver.v
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!!

I2C_driver.v
Peripherals/I2C_driver: Corrected the implementation of the bidirectional SDA pin, fixing the final yosys 0.35 warning

pcf8574_for_HD44780.v
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!

Wishbone_IO_driver.v
Peripherals/Memory: Added support for the litedram DDR memory controller, created a new memory map and updated all relevant code and files including the addition of rudimentary wait state support for the cpu (BIU)
