I found that this has been implemented in a fork of this repository, however it's not easily merged into here as it replaces some other implementation files that I think you wouldn't want in this repo. But for an example of how they implemented it see:
https://github.com/windranger-io/node-plantuml
Since I'm using your version of "node-plantuml" via a dependency of another npm package I can't switch to the fork, so it would be great if your package could also support this.
PUML files can contain the keyword "newpage" which splits the diagram into multiple pages.
Currently when using "node-plantuml" to render such a file, only the first page of the diagram is returned.
When using PlantUML stdout to generate files one can use the "pipeimageindex" parameter to specify which page to render. This was introduced in order to support the VS Code plugin: https://forum.plantuml.net/?qa=6265/specify-page-when-use-stdout
