This packs the stdio implementation from [1] as alternative to what the used standard C lib provides with the intent to provide a thread-safe, smaller, and more feature-complete alternative on newlib targets. Compared to `newlib_nano` this reduces `.text` by a bit more than 200 B while adding support for standard format specifiers such as `RPIu8`, `PRIu16`, `PRIu64`, `%z`, and `%t`. Note that `newlib_nano`'s stdio can be thread-safe in reentrant mode at the cost of RAM (per thread) and latency. Especially the increase in latency can be prohibitive when real time requirements need to be met. [1]: https://github.com/mpaland/printf
