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)

;I got this down to 11428 bytes
org 0x100
output_program:
Added the OUT instruction to be able to properly address I/O and moved printing logic to a device on the I/O space. Also added IRET which is basically just a RET in this case

Peripherals/I2C: Added a CPU I2C driver and wrote a bootloader that uses that to boot from an I2C eeprom I'm happy to have reached 200 commits and with this, version v0.3.0 is functionally ready. I still need to do a fair bit of cleanup and bug fixing though before the actual release. With this commit I added a CPU I2C driver as well as a basic arbiter to have the hardware lcd controller and the software i2c communication pass through the same I2C driver and I2C bus. I also wrote a bootloader that reads code from an i2c eeprom to make sure the hardware works.
