How to calculate latest version impacting the package

[maticzav]

This issue describes the idea behind Semantha's versioning logic.

Presumptions

1. The defined master branch is a basis for all other branches - all prereleases consider master as the only source of truth, regardless of the previous pre-releases.
2. All relevant tags follow package_name@package_version tagging format.
3. Package versions follow semantic versioning where pre-releases state the target master version and iteration of the prerelease (ie. semantha-core@v1.0.2-beta.2- this is the second iteration of code for 1.0.2 release)

Arguments

1. prerelease tag (defaults to none - master),
2. package name.

Idea

The algorithm crawls through the existing repository tags. Each tag is examined to match the name of the package. The algorithm is repeated/paginates through the results until it finds a matching prerelease tag or a master release.
