py-numexpr: updated to 2.8.7

Changes from 2.8.6 to 2.8.7
---------------------------

* More permissive rules in sanitizing regular expression: allow to access digits
  after the . with scientific notation.  Thanks to Thomas Vincent.

* Don't reject double underscores that are not at the start or end of a variable
  name (pandas uses those), or scientific-notation numbers with digits after the
  decimal point.  Thanks to Rebecca Palmer.

* Do not use `numpy.alltrue` in the test suite, as it has been deprecated
  (replaced by `numpy.all`).  Thanks to Rebecca Chen.

* Wheels for Python 3.12.  Wheels for 3.7 and 3.8 are not generated anymore.
