updating the deprecated np.int

[Joscelinrocha]

np.int was a deprecated alias for the builtin int. To avoid this error in existing code, use int by itself.

Hi @Joscelinrocha, it seems like this library is no longer maintained. I think it may be prudent for us (us in the general sense) to open a new fork and disconnect it from this repository so the package can be maintained. Would you like to open up an issue on forking this repository to a new owner? We can discuss who can take over in that case.

Hi. Thank you for pointing this out and suggesting the changes. I haven't been using Wavelet analysis for a while, my apologies for taking so long.

Hi @regeirk @Joscelinrocha

in the PR a np.interp was replaced by interp. The previous one should be recovered or interp should be explicitly imported from numpy

Hi @enekomartinmartinez, thank you for pointing this out. There were other issues as well. I've made a pre-release with some additional updates.
