SteamID converter incorrect bug

[ZK413]

Steam/src/Syntax/SteamApi/SteamId.php

Line 76 in 4a002fb

$formatted = "STEAM_1:$y:$z";

This is fundamentally wrong!

Steam/src/Syntax/SteamApi/SteamId.php

Line 88 in 4a002fb

$formatted = "[U:1:$this->rawValue]";

Also not correct.

CS:GO uses "Universe", but CS:S and CS 1.6 do not.
Example on a real "Steam ID":
CS:GO - STEAM_1:0:18797073
CS 1.6 and CS:S - STEAM_0:0:18797073

In your ID2 and ID3 "Universe" will always be exactly 1 (Public), although for CS:S and CS 1.6 it is exactly 0 (Individual / Unspecified).

Web services and web applications, such as ban lists and Steam ID Finders, also do not use "Universe". that is, for them ID2 and ID3 generated by your code are not correct.

Close attention to "Universes Available for Steam Accounts" and "Types of Steam Accounts".
