Provide some versioning (and maybe upload to crates.io)

[olorin37]

I think, at least we should add git tags and gh releases. To make for users alignments more straightforward. Each release could hold short description of the changes in exposed modules and what alignments are required.

I think it could be uploaded to crates.io, but I do not if there are some cons? (maybe nwind should be separated to different repository or maybe it can be embedded in nperf crate?).
