Custom arguments to d2 compiler

[onsah]

Hi, first of all thanks for this great plugin and diagram tool!

I am using this plugin in my notebook and I am trying to center the diagram generated instead of left aligning. I found that there is a --center flag for this in the compiler, but the plugin doesn't provide a way to pass arguments to the compiler. Would it be possible to allow users to pass arguments? Thank you.

I would like this to be centered intead of being left aligned.
