- heap allocator now makes sure virtual memory pages are mapped before using them. this means we no longer have to use page faults to allocate frames, it is done automatically.
...
- fixed the apic code that caused a page fault. it now writes the correct values at the correct physical address
- improved startup logging including displaying how much RAM is installed.

refactor mega-commit.
...
- reorganised the entire project so that the entire kernel is a single codebase rather than a kernel and a libk.

- 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
