Added color selection in `highlight.sv` due to color blue issues

The blue color of the alignment is confused with the blue of the sv

Currently, I do not plan to change color of SVs. To make them more distinct you can try to change parameter color.palette = c("+" = "colorForPlusAlignments", "-" = "colorForPlusAlignments") to make alignment color more distinct from SVs. However, I agree that SV color should be user defined as well. I will think about solution that works for all function reporting SVs.
