Support deffered types

fix #1

[ThirVondukr]

Thanks for the PR, I'd make a couple of changes, but everything looks good, I also tested it on my work codebase with around 200 dependencies and it works fine, though we didn't have to use deferred types, mostly because it'll probably mean that you'd have a circular dependency somewhere.

I'm not sure, but I think it's safe to assume that all python objects have __name__ attribute? 🤔

Suggested change

	if klass_name := getattr(provider_type, "__name__", None):
	self.type_context[klass_name] = provider_type
	self.type_context[provider_type.__name__] = provider_type

mostly because it'll probably mean that you'd have a circular dependency somewhere.

I needed that due to if TYPE_CHECKING blocks.
If have some abstract class that have dependencies you usually won;t use them in the abstract class itself.
assuming that the implementations are in different modules.

I'm not saying you're doing something wrong, you must've had a valid use case for that, also probably with new python versions when from __future__ import annotation behavior becomes the default that change would have to be made, though, not sure how that would work anyway.

What do you think? I think this can be removed. I can find a valid usecase for this

You should provide the type in the provider I think no?

Not necessarily, in most cases type is derived from the object you pass into provider, e.g. Scoped(Test) would have type Test

I didn't include settings default = None for _cached_dependencies and _cached_type, but I think expecting AttributeError should work too, I think this can be merged
