Add support for crow's foot notation #92

Closed kukimik closed 3 years ago

The diagrams produced currently use the UML notation for relationship cardinality.

How about adding an option to produce diagrams using the crow's foot notation? This looks pretty easy to do and I need this anyway, so I can make a PR if there is any interest in this feature.

(Perhaps in the future Barker's notation could also be included.)

I've noticed https://github.com/BurntSushi/erd/issues/33#issuecomment-485968070, so I'm not the only one who is interested in this.
