- added a new libary libm containing procedural macros for the kernel.

these should be used to include external files and resources in the kernel binary
  at compile time.
  - libm currently supports loading psf-1 formatted fonts
- added two fonts that are included in the binary at compile time
- refactored libk to make the crate structure more organised and maintainable in future.
  new structure:
    - drivers   (hardware interaction)
    - resources (consts and statics included either manually or via macros)
    - std       (standard functions for higher level interaction with the os, for example creating windows)
- added geometry.rs
  - provides the Vec2<T> struct for use with dimensions, coordinates etc.
- added window.rs
  - provides the Window struct for rendering the state of an application to the screen
- added application.rs
  - provides the Application trait for custom programs to implement in order to run
