Add missing dependencies inherited from NewPipeExtractor into NewPipe

- NewPipe uses nanojson and jsoup, despite not declaring them.
- NewPipe depends on NewPipeExtractor, which depends on nanojson and jsoup.
- Gradle lets NewPipe use nanojson and jsoup, but this breaks when I use:

includeBuild('../NewPipeExtractor') {
    dependencySubstitution {
        substitute module('com.github.TeamNewPipe:NewPipeExtractor') with project(':extractor')
    }
}

app/build.gradle
