* Add benchmark for rz_bv_copy_nbits * Improve performance for large to large and small to small bitvector copy * Fix bug with nbit=64 and simplify code * Add test for same bitvector copy * Move bit copy logic to separate function in rz_bits.h + improve comments * Support same vector copy for unaligned case * Expect non-null RzTable in bench utils and add comments * Test against reference implementation instead of hardcoded values
