Add usage example

[malaire]

Add an example of how to use Icon within Html.

Hey, thanks for making an issue!

There's an example in the README.
But I assume you saw that, so I guess it's not clear that Filled.offline_bolt can be used in Html? 🤔
I'll add some type signatures to the example soon.

Made code comment in readme slightly better.

For the record (since I was a bit confused as well):

Icon msg is an alias for Svg msg.

To convert a Svg msg to a Html msg, use the svg function: https://package.elm-lang.org/packages/elm/svg/latest/Svg#svg

Oops, that's actually wrong, you can us an Icon msg directly just like a Html msg!

(The reason why this initially didn't work for me was that I'm using Html.Styled.Html by default, so I had to pass the icon through fromUnstyled first.)

[icidasset]

Yeah, it's an alias for: Int -> Coloring -> Svg msg

I didn't want to make an alias, but I had to because of Elm's limitation on the size of docs.json file 🙈
And yeah exactly, you can just use it together with Html msg

Anyways, thanks @icidasset for the lib, once I figured out how, it was quite convenient to use!
