A time series parser for feeding Numpy arrays to a TimeSeriesInputFn.

Avoids embedding data in the graph as constants.

data A dictionary mapping feature names to Numpy arrays, with two possible shapes (requires keys TrainEvalFeatures.TIMES and TrainEvalFeatures.VALUES): Univariate; TIMES and VALUES are both vectors of shape [series length] Multivariate; TIMES is a vector of shape [series length], VALUES has shape [series length x number of features]. In any case, VALUES and any exogenous features must have their shapes prefixed by the shape of the value corresponding to the TIMES key.
read_num_records_hint The maximum number of samples to read at one time, for efficiency.
