Plots tidy dataframe from a deeptools matrix file to a ggplot2 object.

1	plot_heatmap(df, sort_y = "sum", facets = NULL)

`df`	the df to load.
`sort_y`	how to sort y axis of the heatmap ('region_len', 'sum', 'mean', 'max' )
`facets`	a string for facetting of the plot.

Plots a df from a deeptools matrix tibble.

An ggplot2 plot object.
