// ==================== BASE PACKETS ====================

// The Home Assistant protocol is structured as a simple
// TCP socket with short binary messages encoded in the protocol buffers format
// First, a message in this protocol has a specific format:
//  * A zero byte.
//  * VarInt denoting the size of the message object. (type is not part of this)
//  * VarInt denoting the type of message.
//  * The message object encoded as a ProtoBuf message

// The connection is established in 4 steps:
//  * First, the client connects to the server and sends a "Hello Request" identifying itself
//  * The server responds with a "Hello Response" and selects the protocol version
//  * After receiving this message, the client attempts to authenticate itself using
//    the password and a "Connect Request"
//  * The server responds with a "Connect Response" and notifies of invalid password.
// If anything in this initial process fails, the connection must immediately closed
// by both sides and _no_ disconnection message is to be sent.

// Can only be sent by the client and only at the beginning of the connection
