AV-OS v1.0.0

First major release! I added a file handler to my OS. Right now, I'm storing everything in RAM because it's easy. There is a write limit of only like max 80 chars. This is due to the size of the buffer! I will try to increase it, but it'll be a pain to figure out.

There are three new additional features: ls, read, and write. They're all very self explanatory. You list(ls) files, read them, and write them. If you use write on an already existing file, it will just overwrite it. The reason is because they're stored in a Map type object, and the default behavior is to overwrite. I'll add in a manual check to stop this overwriting.

You'll also notice that this release is way smaller than the other ones. Turns out I was using "cargo bootimage" when I should've done "cargo bootimage --release" to get an optimized version!
