curved attribute not supported in edge

[bitli]

My understanding is that the 'curved' attribute is not supported in Edge,
Apparently this can be corrected by adding it to

@property
    def style_attributes(self) -> List[str]:
        """The style attributes to add to the style tag in the XML

        Returns:
            list: A list of style attributes
        """
        return [
            "rounded",
            "curved",
            "sketch",
            "shadow",
            "flowAnimation",

and adding

       self.curved: Optional[int] = kwargs.get("curved", None)

in the __init__ of Edge, but I do not know the library well so maybe I missed something.
