Update project-layout to reflect changes with go:embed

[ooxi]

According to this repository, assets should be placed below /assets. However, resources to be embedded with //go:embed cannot refer to this directory (to my knowledge?)

Therefore the project-layout should be updated to reflect this change in Go 1.16
