A command parser initially made for quickly making discord bots, but works as a standalone parser too.

Your commands are expected to inherit from the Command class

**Example usage**  
```js

const commands: Command[] = [
    new Command({
        name: 'ping',
        options: [
            {
                name: 'respond',            //
                type: OptionType.BOOLEAN,   // Boolean type expects the parser to have some kind of string -> boolean resolver, see the resolver interface for which methods are expected
                required: true,             // Will throw error if not provided
                defaultValue: true,         // The value that will be given back if no value is given, or if option is required but not provided
                flag: true                  // The parser will look for the option in the "--respond value" form
            }
        ]
    })
]; // Command definitions

const parser = new Parser({commands, prefix: ''}); // Empty prefix
const parsed = await parser.parseMessage('ping --respond');

/**
 * Parsed will be an object cotaining properties args, command, subcommand, and subcommandgroup
 * the args property is an object of the given options mapped by their names, e.g.
 * {
 *   respond: {
 *     ... properties,
 *     value: true
 *   }
 * }
 * 
*/

```

Some of the option types have built-in parsers (e.g. numbers, strings), but others will require the resolver implementation, and in some cases CommandOption extensions.
