How does decoding unordered maps work? 

It seems that current code generator is still outputting code that expects map keys in the exact order that they are defined in cddl.

```
Type = {
   key_a: int,
   key_b: int
}
```

The code generated from this will be a long if statement where the fields are in exact order with && between. So decoding in any order does not work. 

Is there a workaround for this?
