Code generation for Interfaces not working correctly

[maaft]

Hi,

first of all - thank you very much for this great piece of work.
I have some problems with code generation. Attached you find my schema.json and my operations.gql so you can reproduce this.

First, types that implement interfaces are not correctly used in the generated operations.py:

Steps to reproduce:

1. sgqlc-codegen schema schema.json schema.py
2. sgqlc-codegen operation --schema schema.json client:schema operations.py operations.gql
3. Open operations.py and note that BarBaz cannot be found. Either an import is missing or the codegen should put out client.BarBaz instead.

Second, is it possible to get auto-completion in vscode for the generated operations? Currently the derived type seems to be Any. I'm currently using pylance but can of course use something else.

I'll take a look at the bug, that BarBaz should be used inside client.schema, so definitely missing it. But it will take me some time, currently busy with some work projects.

As for your second point, unfortunately that's bit harder due the usage of meta classes. What I plan to do someday is to generate that for queries, see #129

I can surely write a PR. Can you point me into the right direction maybe where the code might fail?

OK, I found it. Will submit a PR soon.

Can you please approve #134 ?
