/**
 * Compute the moving average of a variable.
 *
 * Without zeroDebias, the moving average operation is defined by:
 *   `v += delta`
 * where
 *   `delta = (1 - decay) * (x - v)`
 *
 * With zeroDebias (default), the `delta` term is scaled to debias the
 * effect of the (assumed) zero-initialization of `v`.
 *   `delta /= (1 - decay ^ step)`
 *
 * For more details on the zero-debiasing algorithm, see:
 *   https://arxiv.org/abs/1412.6980
 *
 * Note that this function is completely stateless and does not keep track of
 * step count. The step count needs to be maintained by the caller and passed
 * in as `step`.
 *
 * @param v The current moving average value.
 * @param x New input value, must have the same shape and dtype as `v`.
 * @param decay The decay factor. Typical values are 0.95 and 0.99.
 * @param step Step count.
 * @param zeroDebias: Whether zeroDebias is to be performed (default: `true`).
 * @returns The new moving average value.
