**Is your feature request related to a problem or challenge? Please describe
what you are trying to do.**
The function `try_binary` currently panic on `a.len() != b.len()`:
```rust
pub fn try_binary<A, B, F, O>(
a: &PrimitiveArray<A>,
b: &PrimitiveArray<B>,
op: F,
) -> Result<PrimitiveArray<O>>
where
A: ArrowPrimitiveType,
B: ArrowPrimitiveType,
O: ArrowPrimitiveType,
F: Fn(A::Native, B::Native) -> Result<O::Native>,
{
assert_eq!(a.len(), b.len());
...
```
It is better to let the function return an error in such case because:
1. The return type of the function is a Result;
2. `a.length() != b.length()` is a recoverable error
**Describe the solution you'd like**
1. Replace panic with Err
2. Update the docs
**Describe alternatives you've considered**
We could not do this
