I ended up adding some basic thread stuff, as well as intial
infrastructure to get userspace working.

SSE is now enabled to get rust stuff to work. It was generating invalid
opcode errors because of this.

The build system has been reworked to use multiple different Cargo.toml

is used for dev-dependencies and build dependencies.

Renamed all instances of wireos to wayless. The name of the kernel
changed a while ago but I hadn't actually updated the name in all places
before this.
