Move away from slurping files at compile time

[danielcompton]

With the new ClojureScript AOT cache, we should try and find different ways of doing https://github.com/Day8/re-frame-10x/blob/master/src/day8/re_frame_10x/utils/macros.clj#L5-L15. While it's not user configurable, so won't vary between compiles, it seems like it would be better if possible to take a different approach.

This used to be used to read *.svg files from disk then insert those files as image data uris into the markup.

We now take a different approach where svgs are Clojure hiccup (i.e. just a reagent view) that is rendered embedded into the markup as svg elements instead of a data uri.

So this issue is resolved.
