fix: include cstdio to solve stderr not declared

If you make pip installation with a gcc 13 program, the compilation crash.

To solve this, you need to include cstdio in faster_fifo.cpp

#include <mutex>
#include <cassert>
#include <cstring>
#include <cstdio>

#include <pthread.h>
...

Can this trigger a new tag?

[alex-petrenko]

I do pip releases manually. I'll trigger one in the next few days

would something like this work in the meantime? pip install git+https://github.com/alex-petrenko/faster-fifo.git

[mesaglio]

Yes thats works!
