2022 Demo v2

Changelog:

• Improved SW
• Added options
• Added github button
• Replaced 1 gif because I liked the new one more
• Works offline (Got rid of offline.html, may re-add later)
• Changed size of top button images, no longer does nearest-neighbor scaling ruin the look of the image!

PS: MS to second conversion uses rounding to nearest second, may not be accurate
