> [Rust] Create struct array builder that creates null buffers

> We currently have a way of creating a struct array from a list of (field, 
> array) tuples. This does not create null buffers for the struct (because no 
> index is null). While this works fine for Rust, it often leads to 
> incompatible data with IPC data and kernel function outputs.
> Having a function that caters for nulls, or expanding the current one, would 
> alleviate this issue.
