Let us set baseDir & includeDir with consolidate plugin

Would it be possible to let us pass the baseDir & the includeDir as options to the plugin?

This is the line in the plugin file, we just need to pass them as options
```javascript  
file.contents = await consolidate[this.engine].render(file.contents, {
    cache: false,
    filename: 'base',
    basedir: file.context.homeDir,
    includeDir: file.context.homeDir
});
```
