## Selecting AVX512-VNNI, AVX-VNNI, AVX-VNNI-INT8 etc.
Some mnemonics have some types of encodings: VEX, EVEX, AVX10.2.
The functions for these mnemonics include an optional parameter as the last argument to specify the encoding.
-The default behavior depends on the order in which the instruction was introduced (whether VEX or EVEX came first),
