Add nakedret, unconvert, wastedassign, stylecheck and nolintlint linters to improve code readability - nakedret - https://github.com/alexkohler/nakedret - nakedret is a Go static analysis tool to find naked returns in functions greater than a specified function length. - unconvert - https://github.com/mdempsky/unconvert - Remove unnecessary type conversions - wastedassign - https://github.com/sanposhiho/wastedassign - wastedassign finds wasted assignment statements. - notlintlint - Reports ill-formed or insufficient nolint directives - stylecheck - https://staticcheck.io/docs/checks/#ST - keep style consistent - excluded: [ST1003 - Poorly chosen identifier](https://staticcheck.io/docs/checks/#ST1003) and [ST1005 - Incorrectly formatted error string](https://staticcheck.io/docs/checks/#ST1005)
