Consider a --version option

[tomschr]

Situation

The towncrier script doesn't know --version.

Proposed solution

$ towncrier --version
[... outputs the current version ...]

Should be fairly easy. 😉

I would love to review such a PR :)

Not a pull request, but a short reminder:

That looks like this:

$ towncrier --help
Usage: towncrier [OPTIONS] COMMAND [ARGS]...

Options:
  --version  Show the version and exit.
  --help     Show this message and exit.

Commands:
  build*
  check
  create

However, the output of --version looks a bit strange:

$ towncrier --version
towncrier, version [towncrier, version 21.3.1.dev0]

I think that you need something line @click.version_option(__version__.public())

Note that git version and git --version both work. I don't know etiquette about which or both that should be present. But yeah, I'm definitely pro-version-reporting-thingy (or thingies). :]
