## Summary: This is useful if you want to bind to a type you don't control (or use for other things) but need different serialization than its default. This is a feature gqlgen has and we've found it very useful. For example, in webapp we want to bind `DateTime` to `time.Time`, but its default serialization is not compatible with Python, so currently we have to bind to a wrapper type and cast all over the place, which is exactly the sort of boilerplate genqlient is supposed to avoid. For unmarshaling, the implementation basically just follows the existing support for abstract types; instead of calling our own generated helper, we now call your specified function. This required some refactoring to abstract the handling of custom unmarshalers generally from abstract types specifically, and to wire in not only the unmarshaler-name but also the `generator` (in order to compute the right import alias). For marshaling, I had to implement all that stuff over again; it's mostly parallel to unmarshaling (and I made a few minor changes to unmarshaling to make the two more parallel). Luckily, after #103 I at least only had to do it once, rather than implementing the same functionality for arguments and for input-type fields. It was still quite a bit of code; I didn't try to be quite as completionist about the tests as with unmarshal but still had to add a few.
