[ENH] Add KDTW kernel to be used with kernelKmeans algorithm for time series clustering #1728
Description
Describe the feature or idea you want to propose
The algorithm TimeSeriesKernelKMeans in the API reference for clustering does not take KDTW**, A Regularized Dynamic Time Warping Kernel, as a kernel.
** : https://github.com/pfmarteau/KDTW/tree/master
Describe your proposed solution
Integrate the KDTW given above in https://www.aeon-toolkit.org/en/stable/api_reference/auto_generated/aeon.clustering.TimeSeriesKernelKMeans.html#aeon.clustering.TimeSeriesKernelKMeans
The kernelKmeans algorithm must use the KDTW as a kernel.
