Add example for sqf parsing in readme

[Bluscream]

Can you please add an example of how to parse your format? The stuff i tried below does not work

datetime = "RealTimeAndWeather" callExtension "blu_fnc_getcurrentdatetime";
// _datetime = datetime splitString ",";
hint datetime select 1;
// setDate [datetime select 1, datetime select 2, datetime select 3, datetime select 4, datetime select 5];
