Switch to rrOSt base

[PitchBlackNights]

I recently found rrOSt (rust-raspberrypi-OS-tutorials), and it seems like it would work better than blog_os. It is further developed and already has built-in support for other architectures.

What is the current behavior?

Current circumstance with blog_os is not very good. We are just waiting on v3 of their tutorials because it introduces some changes that we need dearly. blog_os is also hard to work with when it comes to porting to different architectures, because of the nature of its hardcoded x86_64 processor features.

Issue Number: N/A

What is the new behavior?

• Easier to work with other arch's
• Compiles with make
• Uses Docker for needed applications (Ex: qemu)
• Compiles directly to a bare metal disk file, so all you need it to flash it to a drive.
