// used when working with RNA-seq data, where reads may skip long segments
// of the reference between exons. This operator is equivalent to SAM's
// `N`.

// clipped will still be stored in the read.

// have been omitted from this alignment. This may occur if this linear

// trimmed (for example, during error correction or to trim poly-A tails for
// RNA-seq). This operator is equivalent to SAM's `H`.
