 A header-only C++20 coroutine library that brings `async/await` to ROS 2, inspired by [icey](https://github.com/iv461/icey).
 
 Write asynchronous ROS 2 code that reads like sequential code -- no callback nesting, no deadlocks, no `std::mutex`, no state machines -- all on a single-threaded executor.
