**Is your feature request related to a problem or challenge? Please describe
what you are trying to do.**
Have array data which are all with fixed size, when I tried to write the
`RecordBatch` with FixedSizeList column, it failed and reported:
```
"NYI("Datatype FixedSizeList(Field { name: \"item\", data_type: Float32,
nullable: true, dict_id: 0, dict_is_ordered: false, metadata: {} }, 128) is not
yet supported")"
```
**Describe the solution you'd like**
I have searched this error and found at:
https://github.com/apache/arrow-rs/blob/0190408147a34c6c08fcc9ba57443c629c678ca6/parquet/src/arrow/arrow_writer/levels.rs#L161
It looks like not hard to support `FixedSizeList` just like `List` (not
sure), the only thing need to do is constructing the `LevelInfoBuilder` for
`FixedSizeList`.
**Describe alternatives you've considered**
No
**Additional context**
I'm happy to take it if it's simple as I described above
