Review comment:
Maybe `addDict(String name, MinorType keyType)`. Works because the key must
be a scalar and is required. Then the `DictBuilder` simply builds the value
type:
```
scalarValue(MinorType type);
MapBuilder mapValue();
MapBuilder mapArrayValue();
UnionBuilder unionValue();
Foo resumeFoo();
```
Can the value be nullable? (The comment in `DictVector` doesn't say yes or
no.) If nullable is allowed, then only the scalar can be nullable, so maybe add:
```
nullableValue(MinorType type)
```
