Auto suggestions

You can provide suggestions to the input, number and list prompt to enable tab-completions with the suggestions and/or id option. If an id is provided, the values will be saved to the local storage using the id as local storage key. With suggestions you can provide some default suggestions. Both options can be defined at the same time.

deno install you/cli.ts --location https://example.com
