Create a unix-friendly bin

[bloodyowl]

The API should be installable using npm and runnable as a command line :

$ lsdjcrunch crunch ...options
$ lsdjcrunch patch ...options
$ lsdjcrunch crunch-patch ...options
$ lsdjcrunch export ...options

Also, commands should have a --output or -o option for the output file. If not provided, the output file should be piped to stdout

const output = (file: Stream, options) {
  file
    .pipe(options.output ? fs.createWriteStream(options.output) : process.stdout)
}

I'll look into this for the next release.
