WIP working on having suffix versioning; e.g. "0.1.3-rc.2"
semi-working: suffix version bumping works
buggy when making a minor release suffix version bump
better working version; this one bumps properly for major,minor,patch, and suffix
"buggy" with bumping an already-suffixed version with default parameters (patch bump)
working version that bumps suffixes properly :)
