Implemented decoder-modes to support ISA-extensions that conflict with existing instructions
- Added decoder-modes - `ZYDIS_DECODER_MODE_MINIMAL` - `ZYDIS_DECODER_MODE_AMD_BRANCHES` - `ZYDIS_DECODER_MODE_MPX` - `ZYDIS_DECODER_MODE_CET` - `ZYDIS_DECODER_MODE_LZCNT` - `ZYDIS_DECODER_MODE_TZCNT` - Removed `ZydisDecoderInitEx` and the possibility to pass a decoder-granularity (use `ZYDIS_DECODER_MODE_MINIMAL` instead)
