flobernd 943993ae4a Changed the way how user-data is passed to custom formatter-callbacks
* Removed `userData` from the `ZydisDecodedInstruction` struct
* Added `userData` as parameter to all formatter-callbacks
* Added `ZydisFormatterFormatInstructionEx` function with the additional `userData` paramter
