Add svgAttribute option

[gregberge]

Users need to add default attribute to their SVG, like in #82. My proposition is to add a "svgAttribute" option.

Usage in CLI

svgr --svg-attribute "focusable=false"
svgr --svg-attribute "a=b" --svg-attribute "c=d"

At first, all attribute values will be considered as a string

Usage in Node / Webpack

transform("...", { svgAttributes: { focusable: "false" } })
transform("...", { svgAttributes: { a: "b", c: "d" } })

Seems like a pretty solution to the problem i was having.
