optional support for image maps

[anb0s]

It would be good to have option to disable "Added support for image maps".

We are using the Kroki server and it has no support for maps (yet) and we facing broken diagrams with message WARNING in "uml" directive: remote server has returned error 400 in mkdocs builds. The workaround is to set plantuml-markdown = "3.4.3".

Trying to understand the code and contribute, but will take some time...

migrated to new 3.7.0 and do negative test with maps by intention, now it shows the error message from kroki 👍

WARNING in "uml" directive: remote server has returned error 400 on GET: Error 400: Unsupported output format: map. Must be one of plantuml for png, svg, jpeg, base64, txt or utxt.

ok the whole trace shows that we have exception now, because using Kroki but configured PlatntUML:

WARNING in "uml" directive: remote server has returned error 400 on GET: Error 400: Unsupported output format: map. Must be one of plantuml for png, svg, jpeg, base64, txt or utxt.

set

  plantuml_markdown:
    image_maps: false

resolves the exception

Thank You!

Yes, image maps must be explicitly disabled with Kroki, as per request and README, so when they implement image maps no code changes are required (I hope),
