Introduce CTable, a new columnar table class for efficient in-memory data storage using Blosc2 as the underlying compression engine. Each column is represented as a Column object wrapping a blosc2.NDArray with typed, compressed storage. Building on top of blosc2's existing infrastructure, CTable supports append, iteration and column-based queries. This is an early-stage (beta) implementation; the table is always fully loaded in memory. New files: - src/blosc2/ctable.py: CTable and Column class definitions - tests/ctable/: unit tests covering construction, slicing, deletion, compaction and row logic - bench/ctable/: benchmarks comparing CTable against pandas
Add CTable, a columnar in-memory table built on top of blosc2
