Add new get_column_pair_plot

[amontanez24]

Problem Description

As a user, sometimes the plot type selected by get_column_pair_plot is not the best. I'd like to be able to select the plot type to better visualize my data.

Expected behavior

• In the sdmetrics.visualization module, add a method called get_column_pair_plot.
  • If the module/file doesn't exist, create it.
• Use the current get_column_pair_plot function as a starting point.
  • Remove the metadata parameter
  • Add a new parameter called plot_type
    • plot_type can be 'scatter', 'box', 'heatmap' or None
    • By default, use the dtype of the columns to pick.
      • If both are float/int/datetime, then use 'scatter'
      • If one is float/int/datetime and the other isn't use 'box'
      • If neither are float/int/datetime, use 'heatmap'
• Delete the old get_column_pair_plot code.

Additional context

• If provided, verify that a valid plot_type is given.
• We no longer need any of the metadata validation
