**Is your feature request related to a problem or challenge? Please describe
what you are trying to do.**
Currently, the `FixedSizeBinaryBuilder` is built on `FixedSizeListBuilder`,
which introduce some extra computation(create child array, cast from listarray
to binary array). We could simplily it by just using 2 buffer builders (not
tested):
```rust
pub struct FixedSizeBinaryBuilder {
values_builder: BufferBuilder<UInt8Type>,
bitmap_builder: BooleanBufferBuilder,
value_length: i32,
}
```
This may introduce just a little more code, but could save some amount of
computation.
**Describe alternatives you've considered**
We could not do this.
**Additional context**
