Create a QRNN model.
Arguments:

quantiles(np.array): 1D-array containing the quantiles to estimate of
the posterior distribution. Given as fractions
within the range [0, 1].
depth(int): The number of hidden layers in the neural network to
use for the regression. Default is 3, i.e. three hidden

width(int): The number of neurons in each hidden layer.
activation(str): The name of the activation functions to use. Default
is "relu", for rectified linear unit. See
`this <https://keras.io/activations>`_ link for
available functions.
**kwargs: Additional keyword arguments are passed to the constructor
call `keras.layers.Dense` of the hidden layers, which can
