lilos: a minimal async RTOS

This is a wee operating system written to support theasyncstyle of programming in Rust on microcontrollers. It fits in about 2 kiB of Flash and uses about 20 bytes of RAM (before your tasks are added). In that space, you get a fullasyncruntime with multiple tasks, support for complex concurrency viajoinandselect, and a lot of convenient but simple APIs.

I understood some of those words.
