layout of colorbars of annotations

[tzukuo-evotec]

Dear iheatmapr developers,

Thank you for maintaining the useful package. I hope to style my plot but face some challenges. More specifically, I need to modify the appearance of colorbars associated with annotations, such as the orientation per colorbar and the title font. Are there any direct or indirect (e.g., with plotly) methods to change them?

Best regards,
Dr. Tzu-Hao Kuo
