Description
We need to support various bitwise operations:
- [ ] Aggregation functions : `bit_and`, `bit_or`, `bit_xor`, which have the following contexts:
- [X] Sort-based groupby
- [ ] Hash-based groupby
- [X] Reduction
- [ ] Binary transform function: `bit_and`, `bit_or`, `bit_xor`
- [X] Unary transform function: `bit_not`, `bit_count`.
- [ ] Other binary bitwise functions: `bit_get`.
