Allow users select type of slash command arguments

[karelkryda]

This will allow users specify slash command params like this

expectedArgs: [
        {
            "type": 8,
            "name": "role",
            "description": "user role",
            "required": "true"
        },
        {
            "type": 6,
            "name": "user",
            "description": "specify user",
            "required": "false"
        }
    ],

This can be very convenient and works great, however, I suggest keeping the 2 methods (testing typeof of expectedArgs) so as not to annoy those who only use a prefix (or else, one should modify the documentation and add a type checking system for basic commands)

@theo-bnts better?

Or you could add a option parameter for slash commands that overrides expectedArgs

First of all, I apologize for the late response.

Personally, I think this is the easiest way to implement it. But if you insist on adding an argument, I'll do it.
