for some reason bandit wasn't earlier catching the SubElement usage but
now it is, but it's harmless anyway so we'll just suppress it.

without this, the code fence parser was getting thrown off if you didn't
have the pydot extension loaded, which was thwarting backwards
compatibility. this makes the pydot bits look like an attribute to the
vanilla parser, so at least then the vanilla markdown renders as
intended
I didn't like the other figure + figcaption parsers, they either assumed
a lot about usage (e.g. images only), or they were inline parsers that
either wrapped the figure in a paragraph tag (which is incorrect syntax)
or did span trickery (annoying)
so, this handles images and maybe other things, and does things properly
with figures as their own blocks. incomplete but it works with my
images, and should allow for looping (for multi-line content) in the
future?
this is server side, and a more standard format, and thus I like it more
than mermaid, which I've been using at work. but, I really wanted a
server-side option (see my manifesto) for drawing relationship graphs,
for D&D stuff of all things.
this adds an optional 'graphviz' feature to package installation which
consequently depends on pydot
