Importing github.com/ichinaski/pxl - proposal to change the structure of this repo

[VojtechVitek]

Hi, I'd like to import this github.com/ichinaski/pxl into my Go project.

Mind changing the structure of this project, so people can import it? We'd basically need to separate func main() from the pxl implementation:

1. git mv main.go cmd/pxl/main.go
2. rename "main" pkg to "pxl"

Thanks
