feat: add support for Python 3.14

[my1e5]

Co-authored by: Dimitris Iliopoulos dimitris.iliopoulos@gmail.com

This PR adds support for Python 3.14 by bumping the pyo3 and rust-numpy dependencies to version 0.26. This requires a small refactor to the source code. These changes are identical to those made by @diliop in #85, so I've added them as a co-author to recognise their contribution.

Closes #87
