Implement pathbar for sunburst

[ismirsehregal]

In my eyes adding an option to show a breadcrumb trail for plotly's sunburst chart would be a good thing.

Here you can find an example:

Thanks for your great work!

@ismirsehregal Thanks very much for writing in. Great idea!
In terms of roadmap, at the moment we aren't planning on working on this for the next few months, but if anyone here works for an organization that has a software budget, we do accept sponsorship for features, which would enable us to build this feature faster :)

Btw. for treemap traces this is already implemented:

Hi - we are trying to tidy up the stale issues and PRs in Plotly's public repositories so that we can focus on things that are still important to our community. Since this one has been sitting for a while, I'm going to close it; if it is still a concern, please add a comment letting us know what recent version of our software you've checked it with so that I can reopen it and add it to our backlog. Alternatively, if it's a request for tech support, please post in our community forum. Thank you - @gvwilson

I think this still is important especially due to the unequal features comparing sunburst and treemap traces which are otherwise interchangeable.
