[Numpy-discussion] PR to add a function to calculate histogram edges without calculating the histogram

Hi! I've created a PR to add a function called "histogram_bin_edges" which will allow a user to calculate the bins used by the histogram for some data without requiring the entire histogram to be calculated. https://github.com/numpy/numpy/pull/10591#issuecomment-371863472 This function allows
