Simpler decoding

We may simplify decoding with the sets of mask and data. For example decoding ADDI instruction can be written as
if (word & 0x0000707f) == 0x00000013 {
return Instruction::ADDI;
}
then we may rewrite decode function with loop
// pseudo-code
for d in decoding_sets {
if (word & d.mask) == d.data {
return d.instruction;
}
}
