Everything is working great in this build!  So I will be taking about a week break from this.
Well except single pixel drawing on GPU but more on that later.

I included a Hello World program and a screen clear test program running by default.
But I would love to see what programs people can come up with. So definitely fork this and make your own programs for it, and link them in the comments below!

Also I am working on adding more instructions for the cpu and the gpu, let me know what might be useful in the comments and definitely check my in progress updates below!

I am running into an issue with per pixel drawing giving a contention error which doesn't make sense as i have tested the chip. unless the rgb screen col and row pins are also outputs i don't get what is going on.

For now though i'm taking a break from that and working on implementing some more of the OPs.

Here is a list of instructions. I'll add descriptions soon.
Anything with a * before it is not implemented yet.

V4:
So this is the 4th iteration of my CPU lol... I added a few programs for you all to try out and you can even use an assembler now!

V5:
Long time since I updated this... But I've added a GPU! It's called "Color burst" and you can go try out some premade programs I have added on it! There's an assembler guide with GPU dev guide and I encourage you all to go try and make some graphical programs! Also more docs can be found on it's project page.

To-Do:
Increase amount of registers to 8
Make a simple command line
Make a simple operating system for the CPU
