"commands" module implementation

[zikeji]

The plan is already to use yargs-parser to let commands support both positional arguments (the default) and option arguments - like you'd see in a CLI program. This module should depend on an underlying monitor as well.

The command module should have a function for checking permissions of the user running the argument. There will be no "permission" levels, the plan is to extend the base module with a predefined check.

e.g.

export default class ModeratorCommand extends SomniaCommandModule {
  async check(message: Message): Promise<boolean> {
    return true;
  }
}

This way you'd just create base classes for each permission type you want. You can handle logic however you please and even create other classes to run to ease the amount of necessary code.
