use cobra/urfave instead of my own go-commander

Or just leave it there as it is ;)

We can use urfave/cli too, the api looks better than cobra.

package main

	"sort"

	"github.com/urfave/cli/v2"

			return nil

	}

	sort.Sort(cli.FlagsByName(app.Flags))
	sort.Sort(cli.CommandsByName(app.Commands))

	app.Run(os.Args)
