Structurizr plantuml sequence diagram

[pyssling]

I just exported a DynamicView from structurizr as plantuml and was surprised that this did not generate a plantuml sequence diagram. I wouldn't directly consider this a bug, but I definitely feel that it would be good if it could.

Was the choice to not export a sequence diagram intentional? I could probably contribute a fix that makes it generate sequence diagrams, but I'd first like to know if this is wanted behavior. Or maybe there should be an option?

@roxspring Maybe you would like to comment?

Does the c4 model even advocate sequence diagrams?

I guess it could be an option to generate sequence diagrams from a dynamic view model... if all the requisite information is present. Hasn’t been a need for me so far which goes some way to explaining why I haven’t tried this yet!

I actually don't use the PlantUML support myself, and when I put the initial version together, I guess I just opted to create something like a collaboration diagram. Funnily enough there's support for WebSequenceDiagrams, which I also created, but not sequence diagrams in PlantUML. Feel free to submit a PR.

#105 has this improvement. I'll try to add support for parallel sequences later.

C4 doesn't really go into depth on this, but there are a lot of features of sequence diagrams which I would like to see, like alternate flows for example. PlantUML has a much richer vocabulary (for better and worse) than structurizr here, and it would be fun to support more of it.
