Custom Prefixes
The bot prefix is declared in the client constructor, this option supports a string or a function, this is useful for making custom prefixes for each server.
Example
const { Erine } = require('erine');
const bot = new Erine({
    auth: "",
    gateway: {
        intents: []
    },
    async prefix(ctx) {
        // return a string...
    }
});
bot.connect();
