Is your feature request related to a problem?

We sometime needs to resort to do such transformation:

    transformers:
      - addprefix: '"'
      - addsuffix: '"'

or

    transformers:
      - trimprefix: '"'
      - trimsuffix: '"'

Solution you'd like

Let's consolidate into a quote and unquote transformer that performs both operations atomically, improving both performance and code clarity.
