This is looking great, thanks for taking on a more systematic fix for this class of issues!

So I tried this in the past and this doesn't work. As far as I remember, you should not import proc_macro
anywhere except in a proc-macro = true
crate. However, what we can do is convert to proc_macro2 types in askama_derive and then pass that into askama_shared.
I don't love the derive
name of this module, given that I think we might want an attribute macro at some point in the not too distant future, too. Can we use macro
as the name, or is that a keyword?

I replaced proc_macro by proc_macro2.
Actually, I guess I could move everything into generator.rs. It's only 100 lines as is.

That probably makes sense for now, although it just means we should start splitting that up since it's already pretty big. Good start, though!
Before this PR the handling of integrations was done both by askama_shared and askama_derive. This diff lets askama_shared do the work. This will prevent problems like #629, when both packages might come out of sync.
All the hard work in askama_derive was actually done in askama_shared. This PR removes the back-and-forth interaction between the two crates. Now askama_derive is a single re-export of `#[derive(Template)]` which has to be done in a proc_macro crate. This most likely means that askama_derive is "final", unless another derive template needs to be introduced in the future.
Previously askama_shared exported most of it's internals, so askama_derive could use them. This is not needed anymore.

Why do we need this bump?

I un-exported a bunch of symbols. Older askama_shared
versions would break with this update. Every item in https://github.com/djc/askama/blob/main/askama_derive/src/lib.rs#L8-L10 is gone after the PR.

I removed the features section, because they are now handles in askama_shared.
I am not 100% sure, but I guess if I re-added the features, incrementing the patch version only should be fine.

The traits Template and DynTemplate need to be in sync with askama_shared's generator. #647 consolidated the template crating into askama_shared, this PR moves the trait itself.
