Summary: Canonical Huffman trees always emit shallower leaves left of deeper leaves. Therefore these methods are not needed, and are dead code. Differential Revision: D113463813
Summary: Adds `scripts/gen_pivco_huffman_tables.py`, which renders the generated lookup-table headers consumed by the architecture-specific kernels (x86, neon, avx512). It is checked in ahead of the per-architecture kernels that include its output. Reviewed By: kevinjzhang Differential Revision: D109893569
