Fix 1 — Chunk oversized bucket groups (the correctness fix)
ONNXOCRRecognizer::RecognizeBatch now slices each bucket group into chunks of ≤ kRecMaxBatch before submitting to TRT. A frame with 30 crops in bucket 320 produces two back-to-back batched calls (24 + 6), both within the profile, both on the fast path.
Fix 2 — Raise the profile max from 16 to 24 (the performance fix)
The old profile max was 16; your real scenes routinely hit 24. Raising the profile max to 24 means the common 12-plate scene (24 crops) fits in a single batched call with no chunking needed. Scenes with > 24 crops now use chunking, but that's rare.
