github

Add livebook testing CI workflow and fix livebook issues (#20, #21)

Issue #20: Add :bit shuffle support to blosc2 codec
- Implement bit_shuffle/bit_unshuffle in Rust NIF using block-based
  bit transposition (8-element blocks, remainder copied as-is)
- Add BLOSC_BITSHUFFLE constant (2) and dispatch in compress/decompress
- Add :bit to @valid_shuffles and shuffle_to_int/1 in Elixir
- Update tests: replace rejection test with acceptance, add round-trip
- Update README blosc2 options table to include :bit shuffle

Issue #21: Fix errors in livebooks
- 02_compression_fundamentals.livemd: add {:jason, "~> 1.4"} to
  Mix.install, fix Jason.encode!(%{for...}) → Jason.encode!(for...),
  wrap for-comprehension in map value with parentheses,
  replace Kino.VegaLite.new() with returning VegaLite pipeline
- 03_codec_comparison.livemd: remove all Kino.VegaLite.new() calls
- 04_building_storage_systems.livemd: add {:jason, "~> 1.4"} to
  Mix.install, fix Jason.encode!(%{for...}) → Jason.encode!(for...),
  wrap for-comprehensions in map values with parentheses

CI: Add .github/workflows/test_livebooks.yml for livebook_test
on Elixir 1.17.3 / OTP 26.2 (livebook v0.19 is incompatible with
Elixir 1.18+ / OTP 27+). Dependency injected via sed at CI time.

Add livebook_test-issues.md documenting the livebook compilation bug.
