# TS header / adaptation-field-control decode for locating the payload to
# (de)scramble (ISO/IEC 13818-1 §2.4.3.3/§2.4.3.4) — reuses `TsHeader::parse`
# instead of hand-rolling the AFC bit decode a second time. `mpeg-ts`'s own
# `TsPacket` has no mutable-in-place payload accessor (its `payload` field
# borrows immutably), which this crate needs to (de)scramble in place — see
# `src/ts.rs` for why the payload slicing itself stays hand-rolled.
