//! ASTC BISE (Bounded Integer Sequence Encoding) packing tables. BISE packs
//! five trit digits into one 8-bit pattern and three quint digits into one
//! 7-bit pattern; the
//! encoder splits each value into low bits plus a trit or quint digit, then
//! looks up the packed pattern for the whole digit group here and interleaves
//! it with the low bits.

/// Packed 8-bit pattern for each of the 243 (3^5) five-trit groups, indexed by
/// `t0 + 3*t1 + 9*t2 + 27*t3 + 81*t4`.
