🌮 Improvements

Lots of positive updates in this release. If I'm honest, it was mostly just me being confused about correct Promise implementation.

After battling with Promise resolution for three days, turn out text() returns a Promise and I wasn't awaiting it. This tiny bug fix significantly improves card render formatting.
Improved error handling within Promise.all filtering. ty @solominh
Improved CORS handling for Firefox and Chrome. You can download SVGs after opening in a new tab now as well (before the Extension wouldn't fire at all)
Improved communication in the Download all button. It now only downloads available SVG strings instead of zipping up img elements masquerading as SVGs
Fixed asynchoronous messaging when trying to send data to a new tab ty @Deliaz
Style updates to the cards. We gave the grey background behind white SVGs a little padding and lightened it up a bit
Improved the error notification on the cards to more accurately say what is happening for Sprites and CORS
Sprites now dynamically copy their xlink content so exported sprites are now valid SVGs (though they still reference a single id). Thought it was a pretty crafty hack for not being able to access content in the shadow-dom.
