build(deps): bump numpy from 1.15.4 to 1.18.1

[dependabot-preview[bot]]

Bumps numpy from 1.15.4 to 1.18.1.

Release notes

Sourced from numpy's releases.

v1.18.0

NumPy NumPy 1.18.0 Release Notes

In addition to the usual bug fixes, this NumPy release cleans up and documents the new random C-API, expires a large number of old deprecations, and improves the appearance of the documentation. The Python versions supported are 3.5-3.8. This is the last NumPy release series that will support Python 3.5.

Downstream developers should use Cython >= 0.29.14 for Python 3.8 support and OpenBLAS >= 3.7 to avoid problems on the Skylake architecture.

Highlights

• The C-API for numpy.random has been defined and documented.
• Basic infrastructure for linking with 64 bit BLAS and LAPACK libraries.
• Many documentation improvements.

New functions

Multivariate hypergeometric distribution added to numpy.random

The method multivariate_hypergeometric has been added to the class [numpy.random.Generator]{.title-ref}. This method generates random variates from the multivariate hypergeometric probability distribution. (gh-13794)

Deprecations

np.fromfile and np.fromstring will error on bad data

In future numpy releases, the functions np.fromfile and np.fromstring will throw an error when parsing bad data. This will now give a DeprecationWarning where previously partial or even invalid data was silently returned. This deprecation also affects the C defined functions PyArray_FromString and PyArray_FromFile (gh-13605)

Deprecate non-scalar arrays as fill values in ma.fill_value

Setting a MaskedArray.fill_value to a non-scalar array is deprecated since the logic to broadcast the fill value to the array is fragile, especially when slicing. (gh-13698)
