Login messages have a header of 1 byte with an opcode. Some messages also have a size field but this is not considered part of the header.

Offset	Size / Endianness	Type	Name	Description
0x00	1 / -	uint8	opcode	Opcode that determines which fields the message contains.

Body

Offset	Size / Endianness	Type	Name	Comment
0x01	1 / -	ProtocolVersion	protocol_version	Determines which version of messages are used for further communication.
0x02	2 / Little	u16	size
0x04	4 / Little	u32	game_name
0x08	5 / -	Version	version
0x0D	4 / -	Platform	platform
0x11	4 / -	Os	os
0x15	4 / -	Locale	locale
0x19	4 / Little	u32	utc_timezone_offset	Offset in minutes from UTC time. 180 would be UTC+3
0x1D	4 / Big	IpAddress	client_ip_address
0x21	- / -	String	account_name	Real clients can send a maximum of 16 UTF-8 characters. This is not necessarily 16 bytes since one character can be more than one byte. Real clients will send a fully uppercased username, and will perform authentication calculations on the uppercased version. Uppercasing in regards to non-ASCII values is little weird. See `https://docs.rs/wow_srp/latest/wow_srp/normalized_string/index.html` for more info.
