use VersionParsing.jl to parse version numbers

[stevengj]

I notice that you have some parsing machinations for handling foreign version numbers via VersionNumber(string). You might try vparse from https://github.com/stevengj/VersionParsing.jl instead.

Based on https://github.com/stevengj/VersionParsing.jl/blob/master/REQUIRE this would require a mimum Compat 0.62.0. In the process of #21 we are increasing to 0.47.0. Maybe we should increase to 0.62.0 right away?

[stevengj]

No, in general you should list the Compat version that your own code relies upon. The Pkg system is responsible for merging that with the requirements of your dependencies.

I see, thanks.
