fix: retract version v0.3.0; it has an issue that prevents Ooze from …

…running

After introducing #5, running mutation
tests against Ooze itself (and I think it is safe to assume that other projects
too) fails with the following (or similar) error:

```
Error: 	panic: failed type checking for file 'internal/cmdtestrunner/cmdtestrunner.go': internal/cmdtestrunner/cmdtestrunner.go:7:2: could not import github.com/gtramontina/ooze/internal/ooze (can't find import: "github.com/gtramontina/ooze/internal/ooze")
