making_acro_hist_similar_to_R_hist

[mahaalbashir]

This PR updates the ACRO R hist() function to align with Base R's histogram binning and counts behaviour.

Note

Base R's hist() and Python's histogram functions handle interval boundaries differently. R hist() uses right-closed intervals. So if a data point lands on a boundary bin edge, R puts it in the lower bin, while pandas hist() will put it in the upper bin.

Solution:

1. The exact bin edges are computed in Base R and passed to pandas/NumPy.
2. A small offset (1e-7) is added to the upper bounds of each bin to match R's binning behaviour.
