Renaming module will break the build

The module name change from github.com/s0md3v/smap will cause an error with the require statement:

``` 
go install -v github.com/s0md3v/smap/cmd/smap@latest
go.mod:
        module declares its path as: smap
                but was required as: github.com/s0md3v/smap
```
