Tiny update to nanoid-cli which allows generation of multiple ids separated by new line characters. Updates packages to remedy security vulnerabilities.

Main Changes

• Add new CLI argument --number or -n to specify number of ids to generate
• Update documentation to include --number option
• Always end on a new-line character
• Update package version to fix 95 security vulnerabilities
• Add test to ensure --number argument is respected

Comment

I am using nano-id in a project and made a small update to your CLI for convenience, thought I would submit a pull request with the enhancement and updated packages. :smile:
