Change layout to more go-style-ish, replace some modules

* Deejay files, split them to achieve go-style project layout
* Replace logrus with log/slog module to reduce dependencies
* Replace gopkg.in/ini.v1 with github.com/wlevene/ini to make sure all modules BSD licensed
* Update linter config && fix tons of linter warnings
* Update .gitignore
* Update README.md
