Fixed #255

[NoeelMoeskops]

Compiling diff_drive_controller on Fedora (gcc 11.2.1 and glibc 2.33) results in missing definitions in rolling_mean_accumulator.hpp. Adding a simple #include <stdio.h> fixes it though. For more information please see #255.
The Foxy branch could also benefit from this change thought (not sure how to do a pull request for a single commit to two branches).

Also, once you made the changes to the branch, please run pre-commit run --all to pass the format stage of the CI.

Don't worry about Foxy or Galactic, I will cherry-pick this change and add to the next release once merged.

I'm unfamilier with pre-commit. But I ran the command as you said, this is the output:

you should source ros workspace to have access to ament_* commands.
