DeprecationWarning in wavelet.py

../home/milan/Work/clouddrift/clouddrift/clouddrift/wavelet.py:673: DeprecationWarning: Conversion of an array with ndim > 0 to a scalar is deprecated, and will error in future. Ensure you extract a single element from your array before performing this operation. (Deprecated NumPy 1.25.)
  radian_frequency = high_ * np.ones(int(m + 1)) / r ** np.arange(0, m + 1)

I don't recall getting this during testing of the wavelet PR but I'm getting it now. I may be on a more recent NumPy version here.

I have not seen this one. Do you know what the issue is exactly? the int(m+1) and/or np.arange(0,m+1)?

I suspect that m here is a single-element array:

In [42]: np.arange(0, np.arange(1))
<ipython-input-42-be4769809432>:1: DeprecationWarning: Conversion of an array with ndim > 0 to a scalar is deprecated, and will error in future. Ensure you extract a single element from your array before performing this operation. (Deprecated NumPy 1.25.)
  np.arange(0, np.arange(1))
Out[42]: array([], dtype=int64)

should be an easy fix.
