 * The JSON parser can be in one of the following states:
 * 0 - before we've confirmed we have JSON
 * 1 - we have JSON, that is all
 * 2 - We're in a key string
 * 3 - We have a key string and are looking for value
 * 4 - We're in a value string
 * 5 - We have valid key and value pair - can be picked up elsewhere
 * 6/7 - String was too long, clear it out
 * go back to 1 after each key/value pair
 * if a key has a non-string value we ignore it
