// The NHCBParser wraps a Parser and converts classic histograms to native
// histograms with custom buckets.
//
// Since Parser interface is line based, this parser needs to keep track
// of the last classic histogram series it saw to collate them into a
// single native histogram.
//
// Note:
// - Only series that have the histogram metadata type are considered for
// conversion.
// - The classic series are also returned if keepClassicHistograms is true.
