Add a stacked horizontal bar plot

[oree-xx]

Problem

Description

This aims to implement a stacked horizontal bar plot function in plot.py, this will better visualize CC0_RECORDS and CC0_RECORDS_WITH_CC0_MEDIA.
We can easily identify the percentage of records without media and with media on same graph.
Example of visuals: stacked bar chart

Implementation
