Dark mode!

We are gobbling base64 SVGs now

SVGs can now be exported as PNG!

Automatic optimization using SVGO on export!

- 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.

## Under the hood
- Complete codebase rewrite and simplification
- Revised webpack to segment and export modules more sensibly. This saved significant bundle size. We we are at around 800kb. Crazy to think the first releases were like 6mb+.
- Improved class structure of SVG creation. It's easier to read and understand now.

## On top of the hood
- SVG Gobbler now opens in a new Tab instead of on top of the content of the current page. This will set it up to be much more modular and thankfully it won't have to compete with the page styling.
- Improved Sprite handling. Copy and Download should work significantly better
- Improved size determination. This helps SVGs format more dependably in the cards

New functionality
- Isolated SVGs on pages that are opened in a new tab due to CORS can now be copied to clipboard by hitting the SVG Gobbler extension icon.

Fixes
- Fixed a break in gobbling svgs from image sources. They now fetch and error to the console correctly
- Fixed some specificity styling with the buttons on certain sites.
- Removed SVGO from the package. It was increasing the package size by 8x and generally causing problems
- Updated all dependencies
- Fixed a regression with size estimation of icons
- No longer rendering percent based sizing in the cards

- Fundamental exports for PNG and JPG formats implemented (ty @jasonrsadler!)
- Improved SVG size determining logic
- Download All button added (not optimized on export though cause I can't figure it out, halp!)
- Fixed issue with overflow on html not being able to scroll on certain sites
- Removed the viewBox and hidden from view indicators. They were being given too much prominence
