v1.1.1

Upgraded to numpy v2.

v1.1.0

Implemented fixed number of nearest neighbour finding, by returning the neighbour distance and index in the array from which the tree was constructed.

This required adding a new field to the Point struct, which is not used in any other algorithms and adds a small performance overhead.

v1.0.1

Added additional tests and better build flags for the python extension on Windows.
