Get internal version of jsemver itself

[tresf]

Can you please provide a method to fetch version information (of any sort, String, Version, etc) from (this) jsemver package? Some libraries store this in the MANIFEST.MF, others offer APIs to fetch it.

At time of writing this, the only way to calculate this information is to parse it from the JAR filename itself, or to obtain the source code and parse it from CHANGELOG.md or README.md

P.S. Thank you for this wonderful library. :)
