Start the pw_string module

Introduce functions for outputting numbers as strings. Unlike some
snprintf implementations, these functions support 64-bit integers. Also,
very limited floating point support is provided.

These functions are faster than snprintf and never truncate numbers.

Pigweed embedded oriented software libraries

Pigweed is a collection of embedded-focused libraries, which we call "modules". These modules are designed for small-footprint MMU-less microcontrollers like the ST Micro STM32L452 or the Nordic NRF82832. The modules are designed to facilitate easy integration into existing codebases.

Pigweed is in the early stages of development.
