- * Samples must be stored concatenated in a single flat buffer `samplesBuffer`,
- * supplied with an array of sizes `samplesSizes`, providing the size of each sample, in order.
- * The resulting dictionary will be saved into `dictBuffer`.
- * @return: size of dictionary stored into `dictBuffer` (<= `dictBufferCapacity`)

- * Tips: In general, a reasonable dictionary has a size of ~ 100 KB.
- *        It's obviously possible to target smaller or larger ones, just by specifying different `dictBufferCapacity`.
- *        In general, it's recommended to provide a few thousands samples, but this can vary a lot.
- *        It's recommended that total size of all samples be about ~x100 times the target size of dictionary.
