Build Metadata

[dFohlen]

Hi @Neargye,

thanks for implementing semver! We've been using it in our project since version 0.1.8, but had to add the build metadata ourselves. It would be nice if you could add this also to the official repo.

https://semver.org/#spec-item-10

We use it to store and compare the build hash.

Example: 1.4.0-alpha.1+6703c608
