Cache all strings

[matray]

Re-using codecs becomes a really memory costly operation, even lightly CPU intensive too - creating codec strings over and over again that can't be de-duped or reused. This is an attempt to cache all strings used for "names". Very open to feedback here.

Before submitting a pull request, please make sure the following is done:

• Fork the repository and create your branch from master.
• Run npm install in the repository root.
• If you've fixed a bug or added code that should be tested, add tests!
• Ensure the test suite passes (npm test).

Note. If you find a typo in the documentation, make sure to modify the corresponding source (docs are generated).

Re-opening this one, it's not the most fp implementation, but I'm open to feedback there :)

Ha! closing again, discussed internally with my team, looks to be user error that these are being created over and over again.
