advanced_image_processing: region_properties was changed again due the items and keys methods of  RegionProperties instances not behaving in a backwards compatible way.
wavelet_transform: Made optional whether to return intermediates of wavelet transform or not.
wavelet_transform: Created function local_maxima_properties. This does some of the work present in wavelet_denoising as it finds local_maxima and creates a NumPy structured array to contain the contents just as region_properties does.
