// Use this file to deploy or delete bot commands
//      node deploy-commands.js                                    - deploy all commands in ./commands/ using .env
//      node deploy-commands.js ENV_NAME                           - deploy all commands using custom not default env
//      node deploy-commands.js -x ignore.js,test.js               - deploy all commands but ignore ignore.js and test.js commands
//      node deploy-commands.js -d ID                              - delete a global command with id
//      Args Usage:
//          -x <filename>: Ignore a specific file when deploying commands.
//          -d <command_id>: Delete a command by its ID.
