Title: Minor cleanup.

1. Removed unused variables for `rescue`'d exceptions.
2. Removed `StringIO` from `Formatters::Base#format`.
3. Raising `NotImplementedError` where appropriate (as discussed in #27) and `ArgumentError` [here](https://github.com/KL-7/twitter-cldr-rb/commit/53927fc8b4a75d5de5b74d60ea9e0ec9c79fd4b1#L0R199).
