FeatureRequest: integrate ` heatmap_legend_side` into ` heatmap_legend_param`?

[wbvguo]

Dear ComplexHeatmap developer,

Hope you are doing well.

I found the parameter heatmap_legend_side only works in draw(...), but not in heatmap_legend_param=list(...). Would it be possible to integrate the heatmap_legend_side into the heatmap_legend_param as a whole pack that controls the behavior of legend (color, label, title, position, etc)?

Besides, currently the heatmap_legend_side only support the "top", "bottom", "right", "left" position. Could we also allow for a flexible position placement such like "bottomright" or hjust=1 or sth similar?

Thanks!
