Nested updates support

[Eldow]

@mlipscombe tell me what you think about it. I will provide the tests ASAP.

I'm pretty sure there is a nicer way than includes('updateBy') to detect an updater field in the input but I'm not very used to what's available.

is this working with infinte nested mutations?

[Eldow]

Yes it should be.

@Eldow I'm also interested in getting this merged. There are a couple of existing integration tests that fail. I've fixed that and also added tests (which lead to a few minor changes). I have opened a PR for your fork with those changes. Would you please have a look?

[Eldow]

Hello @andrisak thanks a lot for your contribution, it looks perfect to me :) Those are definitely relevant changes.

I am really interested by this feature; when will this one be merged ?

@mlipscombe Is this repo considered unmaintained now? This seems like a pretty desirable PR and hasn't had any updates since 2021

bumping this again, this would be a helpful feature. alternatively, throwing an error or warning instead of silent non-updates would save debugging time.
