Add CustomAttr function

[Lord-Y]

Hello @markuswustenberg Thank you for creating gomponents. This is such a clean and easy way to generate HTML code.
So far everything have been pretty good for me.
The only thing I think is missing is a custom attribute func like:

func CustomAttr(k, v string) g.Node {
	return g.Attr(k, v)
}

It's very useful when you what to add hreflang attribute or any other attribute that is not currently supported.

What do you think?

Hi @Lord-Y. Just use g.Attr directly and you have your custom attribute. 😊

That's true 🤣

That said, if there are attributes missing that you think should be included (standard HTML 5, not deprecated, browser-specific, or experimental), feel free to file an issue or make a PR! 😊
