* First pass at Python 3.11 support

* Update 'whats new'

* Update build_requirements for different python versions

* Fix docs

* Empty commit for CI

* Use lowest supported numpy (==) for building instead of max compatible (~=)

* Make min numpy 1.21.3

* Use lowest supported version of scipy when building

* More scipy hackery

* https://github.com/scipy/scipy/blob/26a77da3a4ca126a943a331c1aa6ef3915b0d501/pyproject.toml#L41
