Implemented SELECT transformer to project fields from parser ## Contributor Comments This is a simple PR to add FieldTransformation capabilities to the parsers allowing basic projection. There are definitely better ways to implement this as reflected in the comments, but those would need a wide ranging refactor of FieldTransformations, so I've decided to shelve that for now. ## Pull Request Checklist Thank you for submitting a contribution to Apache Metron.
