## Thread local variables for Rayon thread pools

This crate provides a simple `ThreadLocalCtx` struct that allows to store efficient thread-local state that gets built by a lambda.

It is incredibly useful in multithreaded processing, where a context needs to be used that is expensive to clone. In the end, there will be no more clones occuring than number of threads in a rayon thread pool.
