Re-fit entity matcher model

Creates a new model by re-training an existing model on existing data but with additional true matches. The old model is not changed. The new model gets a new id and new external id if newExternalId is set, or no external id if newExternalId is not set. Use for efficient re-training of the model after a user creates additional confirmed matches.

Array of objects [ 0 .. 2000000 ] items

List of source entities, for example, time series. If omitted, will use data from fit.
