//! Bit-ordering and parameter-layout tables for AMR-NB, from TS 26.073.
//!
//! Two families, both from `bitno.tab`:
//!
//! - `SORT_*` maps payload bit position to codec bit position, exactly as
//!   AMR-WB's tables do. RFC 4867 carries the bits sorted by subjective
//!   importance rather than in decoder order.
//! - `BITNO_*` gives each parameter's width in the order the decoder reads
//!   them. This is what makes eight genuinely different frame layouts
//!   tractable: the reference expresses each as a flat list rather than as
//!   code, and so does this.
//!
//! Generated by `tools/gen_nb_tables.py`, which checks each sorting table is a
//! true permutation and that the two families agree on every frame length --
//! they are independent tables in the reference, so a disagreement means one
//! was transcribed wrong.
