I went ahead and optimized `split_streams_variable`. The time for FLBA(16)
dropped a lot.
```
encoding: dtype=parquet::data_type::FixedLenByteArray,
encoding=BYTE_STREAM_SPLIT #7
time: [264.19 µs 267.64 µs 271.35 µs]
change: [-70.668% -70.084% -69.554%] (p = 0.00 <
0.05)
Performance has improved.
Found 1 outliers among 100 measurements (1.00%)
