datatype typo: `float_` not defined

any OS
wxPython 4.2 from pypi
stock python 3.10

Description of the problem:

An unknown datatype appears in the source: float_ instead of float. This happened when changing the datatypes from N.<dtype> to <dtype> because of the deprecation of numpy datatypes float and int. Changing it to float fixes the problem.

The FloatCanvas demo runs nevertheless but behaves rarely.
