Reduced numbers to be sorted in gnome_sort.asm to fit in lcd, fixed hlt on real hardware, slowed down cpu, increased lcd fifo and with that I almost got gnome_sort.asm working perfectly on real hardware

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!

The CPU works on real hardware for the first time! I added an adjustment for ram size, added control for a led and a test program for it. On the fpga board there is an actual led there that I used to verify functionality
