Short demo of upcoming go 1.16 "io/fs" package and file embedding feature.
Depending on how the binary is built, either with dev build tag or without,
the assets/ folder will be embedded in the code (without dev tag), or the
assets will be read from the filesystem.
Run make to build the demo. The embed-demo will have the assets folder
compiled-in. The embed-demo-dev will use the filesystem to obtain the assets.
