Ability to skip ldjson-stream serialization?

At present the module always serializes objects back to strings using JSON.stringify such that the example code of:

fs.createReadStream('data.csv')
  .pipe(require('ldjson-csv')())
  .on('data', function(obj) {
    // obj is a javascript object
  })

Is actually:

fs.createReadStream('data.csv')
  .pipe(require('ldjson-csv')())
  .on('data', function(obj) {
    // obj is a serialized JSON string
  })

In my particular use case, I really wanted the object and reparsing the JSON seems a little inefficient (although it would be ok in my case). I'm wondering if you'd except a PR for me to make the serialization optional, such that:

fs.createReadStream('data.csv')
  .pipe(require('ldjson-csv')({ stringify: false }))
  .on('data', function(obj) {
    // obj is a javascript object
  })

would work...

Start at the module entry point used by require('ldjson-csv')() and trace where parsed objects are serialized with JSON.stringify. Verify that stringify:false emits JavaScript objects while the default retains the current serialized-string behavior.
