With nexedi/wendelin@3f887532 and nexedi/wendelin@b4c22280 we already removed numpy security duplications:
this code already exists in ERP5 (with nexedi/erp5@a254bf50).
But we still missed some code parts: https://lab.nexedi.com/nexedi/wendelin/blob/b4c222803027a2d0d0fae793a4f16d4bea85f87d/product/Wendelin/__init__.py#L49-52
(perhaps because they looked different between erp5 and wendelin).

Furthermore with nexedi/erp5@79fa584e the last
numpy parts which only existed in Wendelin were also migrated to ERP5,
which is why we can finally also remove this from Wendelin.

Now all numpy related RestrictedPython definitions can be found in
the ERP5 codebase and they are no longer distributed over both ERP5
and Wendelin.

Add Zope4 support, while keeping Zope2 support for now

See merge request nexedi/wendelin!110

Base_wendelinTextToNumpy just takes a string and pass it to numpy.load,
but numpy.load will load pickles (problem from https://github.com/numpy/numpy/issues/12759 ).
Therefore we disallow loading pickles here until this becomes the
default in newer numpy versions.

self.publish() had a bug regarding status code for empty responses on
Zope2 and that bug was fixed in Zope4, this adjust the code to support
both versions.

this is already done in ERP5

See merge request nexedi/wendelin!111

   All modules should use this base category.

With erp5@a254bf50 numpy
was allowed in erp5 upstream Restricted.py. There is no need for any
duplication in wendelin.
