Changing color scale pallete in heatplot from enrichplot

[bartlosz]

Dear YuLab team, I am trying to change default colour scale palette in heatplot to draw it by cowplot::plot_grid by I cannot find any ggplot solutions to work. Tried scale_color_brewer() and set_theme from ggplot but it didn't work. I am hoping for some suggestions? Thank you for this nice and useful package! Bartek
