Support arbitrary HTML Attributes

[jherdman]

To aid with tooling like AlpineJS the following would be nice:

<%= inline_svg_pack_tag "my/svg.svg", 'x-show': 'foo' %>

Ideally any HTML attribute ought to be supported.

Let's look at the options table:

key	description
id	set a ID attribute on the SVG
class	set a CSS class attribute on the SVG
style	set a CSS style attribute on the SVG
data	add data attributes to the SVG (supply as a hash)
size	set width and height attributes on the SVG Can also be set using height and/or width attributes, which take precedence over size Supplied as "{Width} {Height}" or "{Number}", so "30px\45px" becomes width="30px" and height="45px", and "50%" becomes width="50%" and height="50%"
title	add a \<title> node inside the top level of the SVG document
desc	add a \<desc> node inside the top level of the SVG document
nocomment	remove comment tags from the SVG document
preserve_aspect_ratio	adds a preserveAspectRatio attribute to the SVG
aria	adds common accessibility attributes to the SVG (see PR #34 for details)
aria_hidden	adds the aria-hidden=true attribute to the SVG
fallback	set fallback SVG document

I think a great many of these would benefit from a change in API that allowed for arbitrary HTML attrs.

Hypothetical future API:

<%= inline_svg "foo.svg",
  attrs: { aria: { hidden: true }, class: "fill-current", id: "123" },
  svg: { title: "My foo" },
  fallback: "whatever"
%>

Thanks for the suggestion. Definitely not against this idea in principle but would only be possible if somebody from the community were prepared to work on this.

Obviously this kind of API change would require a major version bump. Version 2.0 is around the corner, so if anybody wants this to happen soon, and can spare the time to work on it, please let me know.
