Is there a way to query modrm presence?

[dbalsom]

Thanks for the great crate -

Quick question, because I've searched the docs and come up blank.

Is there a way to query if an instruction has a modrm byte? Maybe I'm missing a simple way to do it.

I've currently got a kludgy workaround looking at the disassembled string for brackets, but surely...

I think the simplest thing would be adding 'has_modrm' and 'has_sib' on Instruction.

Or maybe get_address_offsets on Decoder, like we have get_constant_offsets, could return an AddressOffsets that has the offset of the modrm byte, sib byte, and displacement.
