Bug fixes for taper error

This release mostly fixed errors when using the latest scipy (1.13.0 as of the test), which caused incompatibility with the ObsPy taper function with "hann" window. The nested ObsPy taper function uses hann window from scipy.signal. This release also updated the notebooks/seisgo_download_xcorr_demo.ipynb notebook with the latest seisgo usages. Minor fixes in noise module replacing numpy.int with int'. Same for numpy.float`.
