Tag releases to support go.mod semantic versioning

[ciehanski]

Seems like this has been an issue before, but I wanted to bring it to attention again. I am using go.mod and since you have a release submitted on the repo, it defaults to semantic versioning which defaults to the v1.0.0 release of go-humanize which is over 2 years old. Some of my projects have been using your old release for quite some time. Please tag releases :)

v1.0.0 release of go-humanize which is over 2 years old

There is exactly one commit since v1.0.0: v1.0.0...master

I just sent PR that adds go.mod: #93

@dustin If you could merge that PR and then tag v1.0.1, that would greatly help some of us.
