Suggest static compiled dot for easy installation on shared hosting

[micschk]

Hi, your module made me aware of Graphviz as a way to visualize structural data, thanks for this!

I am now using dot to visualise workflows in a (yet unpublished) workflows-module, so for this dot needs to be installed on the live server.

As it can be quite hard to get Graphviz/dot installed on a server if you don't have admin permissions, I've published a pre-compiled version which you can just upload and use via FTP. It may be nice to add this to your README and/or suggest it when installing via composer?
