A simple utility for creating and serializing semantic versions.
The utility is primarily used by the helper crates which create and sign binaries for Betrusted/Precursor. This includes utilities that create the EC and the SoC images. This need for cross-platform packing of versions is what drives this into a separate crate that can be included by both build systems.
This crate is designed to be runnable on host OS, Xous, or EC. The std feature
must be turned off to run on the EC.
