This reverts commit 45721d1e.

"application/octet-stream" whcih makes accessing object via ERP5-ish UI impossible.
The reason for this is that a call to _range_request_handler was always setting this "Content-Type" header.
This before switch to Zope4 remained unoticed. Fix now.

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.
