WikiProjects banners are not correctly detected when inside of {{WikiProject banner shell}}

[zanhecht]

The script lists WikiProject banners on the talk page, but the script does not count WikiProject banners wrapped in {{WikiProject banner shell}}. This also causes redundant WikiProject Biography templates to be added if the "biography" box is checked.

I noticed a comment in the source that "We only want top level templates", but an exception should be made for {{WikiProject banner shell}}.

Is there any script that does this correctly? I think there are some 4-6 scripts that add project banners to the talk page:
*AFCH
*AFC-submit-wizard.js
*AFC-add-project-tags.js
*Various draft sorter user scripts

It's good most of these scripts are now at least using the same data source. Ideally they could even use the same logic for adding/removing banners - because that's definitely involved.

I have a draft sorter script that both detects and adds WikiProject banners within the banner shell, but its logic is a lot simpler that the AFCH script: https://en.wikipedia.org/wiki/User:Ahecht/Scripts/draft-sorter.js

The AFCH script overcomplicates some things. It would be worth it to consider whether Ahecht's code can be adapted for use here.
