I've pushed the concat updated implementation so you can run the benchmarks
locally, for me:
```
concat i32 1024 time: [241.43 ns 244.65 ns 247.98 ns]
change: [-47.617% -46.762% -45.826%] (p = 0.00 <
0.05)
Performance has improved.
Found 3 outliers among 100 measurements (3.00%)
2 (2.00%) high mild
1 (1.00%) high severe
concat i32 nulls 1024 time: [350.99 ns 352.72 ns 354.66 ns]
change: [-45.490% -45.239% -44.996%] (p = 0.00 <
0.05)
Performance has improved.
Found 6 outliers among 100 measurements (6.00%)
3 (3.00%) high mild
3 (3.00%) high severe
concat 1024 arrays i32 4
time: [7.5176 µs 7.5277 µs 7.5396 µs]
change: [-89.988% -89.963% -89.935%] (p = 0.00 <
0.05)
Performance has improved.
Found 12 outliers among 100 measurements (12.00%)
2 (2.00%) high mild
10 (10.00%) high severe
