Wrong type for count if parsing rules

[razaqq]

SteamQueryNet/SteamQueryNet/SteamQueryNet/Utils/DataResolutionUtils.cs

Line 109 in c7f1e8a

byte itemCount = rawSource[RESPONSE_CODE_INDEX];

For players this is correct (its a byte), but for rules this is wrong and needs to be 2 bytes (short/Int16)
