Enable Sourcelink so that it is possible to step into the code when debugging.

I can look at this one if it's available?

@rikrak Hi, sorry for not getting back timely. Yes if you would like to look at this it would be very welcome.

In fact, the entire build/publish pipeline for the v3 version needs some work, so please don't hesitate to make suggestions if you have ideas on how to solve it.

Cool. It might be a couple of weeks 'til I can get time to look into this, but it's on my to-do list :-)
