reorder cell-pairs in netVisual_bubble failed

[Statekeylablin]

Thanks for your awesome work on cellchat. I've met a problem when I use the function netVisual_bubble in cellchat when I reorder the cell pairs by changing the cell type names in source.use or target.use. The result remains to be ordered by the initial letter of the cell type names. Could you please figure it out?

@Statekeylablin Thanks for bringing it out. Can you please help to do it as recently I am busying with deadlines and teaching.
