py-numexpr: update to 2.8.3.

Changes from 2.8.1 to 2.8.3
---------------------------

* 2.8.2 was skipped due to an error in uploading to PyPi.
* Support for Python 3.6 has been dropped due to the need to substitute the flag
  `NPY_ARRAY_WRITEBACKIFCOPY` for `NPY_ARRAY_UPDATEIFCOPY`. This flag change was
  initiated in NumPy 1.14 and finalized in 1.23. The only changes were made to
  cases where an unaligned constant was passed in with a pre-allocated output
  variable:

```
    x = np.empty(5, dtype=np.uint8)[1:].view(np.int32)
    ne.evaluate('3', out=x)
```

  We think the risk of issues is very low, but if you are using NumExpr as a
  expression evaluation tool you may want to write a test for this edge case.
* Thanks to Matt Einhorn (@matham) for improvements to the GitHub Actions build \ 
process to
  add support for Apple Silicon and aarch64.
* Thanks to Biswapriyo Nath (@biswa96) for a fix to allow `mingw` builds on Windows.
* There have been some changes made to not import `platform.machine()` on `sparc`
  but it is highly advised to upgrade to Python 3.9+ to avoid this issue with
  the Python core package `platform`.
