Add another at any position

[janno42]

Currently, additional form entries can be added only at the end of formsets by clicking "add another".
For all sortable forms, this should be possible at any position to faster create new entries at the dedicated position.

I have looked into this issue. For dynamically creating forms in formsets, we use django-dynamic-formset. The position of "add another" is hardcoded there. After talking to @janno42, we decided that a custom solution on top of this library is probably not worth it. Therefore, we will not implement this feature at this time.

There is an issue for django-dynamic-formset: elo80ka/django-dynamic-formset#159
However, they seem to currently be unmaintained.
Some people have suggested to transfer the project to jazzband in elo80ka/django-dynamic-formset#156, but it doesn't look like there's a lot happening there.
