Tried with and without memchr and looks like memchr improves performance :
```
Implementation │ Spark (ms) │ Comet (Scan+Exec) │ Speedup │
├──────────────────────────┼─────────────┼─────────────────────┼──────────┤
│ WITH memchr (current) │ 1336 (1.0X) │ 826 ms │ 1.6X │
│ WITHOUT memchr │ 1341 (1.0X) │ 1469 ms │ 0.9X
```
