resample error in python==3.14/numpy==2.4.2#39

Description

the error is:

    r = samplerate.resample( y, ratio, res_type )  #simpleAPI

ValueError: cannot resize an array that references or is referenced
by another array in this way.
Use the np.resize function or refcheck=False

happens when ratio is non-int with fractional non-power-of-2 ( e.g. 3 works, 1.5 works, 1.51 does not).
e.g.

import samplerate,numpy
a = numpy.array( range( 44))
samplerate.resample( a, 1.51)

fails for numpy==2.4.2 but works ok with numpy==2.3.4

Note: the recent docs for numpy.resize mention something similar, may or may not be related: https://numpy.org/devdocs/reference/generated/numpy.ndarray.resize.html

    @svilendobrev This issue was raised in #35 and should have been fixed by #36 .

    I checked that your test code works with python 3.14.3, numpy 2.4.3, and samplerate 0.2.4.
    Could you please update to the latest version of samplerate (0.2.4) and try again?

    hm. Yes. it works after re-installing. Seems some cached old version was in the way. Thank you and sorry for the noise
