1. I do like having the type string there but I can appreciate that it's duplicative.
2. Yeah. what about a construct like
```
"Value": { "bytes": 16 },
"Type": "PLTRELSZ",
},
....
"Value": { "Shared library": "[D]" }
"Type": "NEEDED"
},
...
"Value": {"value": 4096 },
"Type": "HASH"
},
```

and so on?
