Handle multiple inflows

[Hveemos]

Thank you for a great package!

However I struggle with multiple inflows: I have three cohorts (inflows): 2010, 2014, 2018. Each cohort goes through one or two phases untill it might reach the final phase 3. Thus, I want some sort of stacked sankey plot. Here is my data:

* Example generated by -dataex-. For more info, type help dataex
clear
input str17(source destination) float layer double value
"Phase 1"        "Phase 2"        1 63
"Phase 1"        "Phase 3"        1  2
"Phase 2"        "Phase 2"        1 31
"Phase 2"        "Phase 2"        2 52
"Phase 2"        "Phase 2"        3 31
"Phase 2"        "Phase 3"        1 40
"Phase 2"        "Phase 3"        2 28
"Phase 2"        "Phase 3"        3 16
"Phase 2 (2014)" "Phase 2 (2014)" 2 44
"Phase 2 (2014)" "Phase 2 (2014)" 3 30
"Phase 2 (2014)" "Phase 3 (2014)" 2  8
"Phase 2 (2014)" "Phase 3 (2014)" 3 10
"Phase 2 (2018)" "Phase 2 (2018)" 3 45
"Phase 2 (2018)" "Phase 3 (2018)" 3 13
end

The command works pretty well when I only use the two first cohorts:
sankey value in 1/12, from(source) to(destination) by(layer)

But when I use all three there is some ugly overlap

sankey value, from(source) to(destination) by(layer)

I don't know if this is a bugg or a request for enhancement though.

And also, it would be nice to be able to add some xlabels indicating the name of each layer.

This is definitely a bug. Will fix it over the weekend.
