ergodox_json fixture file isn't for ergodox

The Ergodox Fixture file doesn't appear to be for an ErgoDox, since it has 84 keys.

Lets put them in a separate repo, that way we can access them from both repos.

If we put them in this repo, we can add a method to the gem that outputs them, and then we will be able to access them from both repos.
