add_persona_from_details

Add a new persona in the given PersonaStore based on the `details` provided.

If the target store is offline, this function will throw IndividualAggregatorError.STORE_OFFLINE. It's the responsibility of the caller to cache details and re-try this function if it wishes to make offline adds work.

The details hash is a backend-specific mapping of key, value strings. Common keys include:

• contact - service-specific contact ID
• message - a user-readable message to pass to the persona being added

If a Persona with the given details already exists in the store, no error will be thrown and this function will return `null`.

Parameters:

parent	an optional Individual to add the new Persona to. This persona will be appended to its ordered list of personas.
persona_store	the PersonaStore to add the persona to
details	a key-value map of details to use in creating the new Persona

Returns:

the new Persona or `null` if the corresponding Persona already existed. If non-`null`, the new Persona will also be added to a new or existing Individual as necessary.
