Exception in parsing "1.37.0-1"

[tirolerstefan]

Nice header-only project, but unfortunately not usable for me, because the following code throws an exeption (semver::version::from_string invalid version).

semver::version vNew = semver::from_string("1.37.0-1");

According to semver.org, this is a valid version with "pre-release" tag.
