Incompatible servers

Code:

const mc = require('minecraft-protocol');

if(process.argv.length < 4 || process.argv.length > 6) {
  console.log("Usage : node echo.js <host> <port> [<name>] [<password>]");

Start with the provided echo.js reproduction and test the listed Hypixel, Mineplex, and 2b2t servers. Inspect the update_time deserialization failure in the stack trace and src/transforms/framing.js for the 2b2t framing error. Done means the client handles these server connections without the reported protocol errors.
