feat: reduce image size of `*.png` images

[evanwporter]

The size of the *.png images could potentially be reduced by running over all the images with imagemin and imagemin-pngquant.

I haven't explored this too indepth, but I first made a simple vite plugin that ran the imagemin app over all the images before adding them to the dist, but it took too long so I scrapped it. However from what I could tell the images did seem to be smaller if only by a few megabytes (I'm not sure how many of the images the app actually go to though).

I think this is definitely worth a try, if we can reduce the image size without affecting quality too much. A huge chunk of the bundle size is those Home images. I don't want to get rid of the images, or to make them too crunchy, but there's gotta be a way to get them at least 20% smaller
