Since go1.16, there are built in tools that allow for embeding
filesystem inside the binary. We now make use of the `embed` package to
have all files put into the binary, removing the need to generate the
files and removes dependencies

1. Use a submodule for dir-index-html. This isn't a go dependency and treating
it like one is more trouble than it's worth. We don't actually need to
checkout the submodule unless we need to regenerate the assets.
2. Avoid a runtime dependency on dir-index-html (may shave a few bytes off the
final binary?).
3. Remove unused code.
4. Avoid bundling unused files.
5. Switch to a maintained version of go-bindata.
6. Use go mod to manage go-bindata.
