Update ndarray requirement from 0.13 to 0.14

[dependabot]

Updates the requirements on ndarray to permit the latest version.

Changelog

Sourced from ndarray's changelog.

Version 0.14.0 (2020-11-28)

New features

• Zip::apply_collect and Zip::par_apply_collect now supports general elements (not just Copy) rust-ndarray/ndarray#817
• New function stack (new behaviour!) by [@andrei-papou]

Enhancements

• Handle inhomogenous shape inputs better in Zip, in practice, guess better whether to prefer c- or f-order for the inner loop by [@bluss] rust-ndarray/ndarray#809

API changes

• The old function stack has been renamed to concatenate. A new function stack with numpy-like semantics have taken its place. Old usages of stack should change to use concatenate.

  concatenate produces an array with the same number of axes as the inputs.
  stack produces an array that has one more axis than the inputs.

  This change was unfortunately done without a deprecation period, due to the long period between releases.

• Enum ErrorKind is now properly non-exhaustive and has lost its old placeholder invalid variant. By [@Zuse64] rust-ndarray/ndarray#848

• Remove deprecated items:

  • RcArray (deprecated alias for ArcArray)
  • Removed subview_inplace use collapse_axis
  • Removed subview_mut use index_axis_mut
  • Removed into_subview use index_axis_move
  • Removed subview use index_axis
  • Removed slice_inplace use slice_collapse
  • Undeprecate remove_axis because its replacement is hard to find out on your own.

• Update public external dependencies to new versions by [@Eijebong] and [@bluss]

  • num-complex 0.3
  • approx 0.4 (optional)
  • blas-src 0.6.1 and openblas-src 0.9.0 (optional)

  rust-ndarray/ndarray#810

[dependabot]

Looks like ndarray is up-to-date now, so this is no longer needed.
