Simple command-line tool to manipulate JWT tokens

Run jwt-tool without any parameters to start interactive console UI:

./jwt-tool

Run jwt-tool with command line parameters to trigger batch mode

./jwt-tool <command> [<parameters>]
./jwt-tool --help

The only supported command for now is create. Parameters are:

• --to-clipboard to export generated JWT token to clipboard
• --payload <name> <value> to add key-value pair to JWT payload/claim. Required claims are user_id and email.
