Split build name and build number

[mrverdant13]

Description

The version often includes a version name and a version number, i.e. 4.2.3+45.

It would be useful to generate two different constants:

const buildName = '4.2.3';

const buildNumber = '45';

const packageVersion = '$buildName+$buildNumber';

Likely going to leave it as-is. You can always pop this bit out with package:pub_semver
