   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   
   I want to write this to create an array without nulls (as I am used to using this syntax all over rust codebases): 
   
   ```rust
   let value_data: Int8Array = [10_i8, 11, 12, 13, 14, 15, 16, 17]
     .into_iter()
     .collect();
   ```
   
   
   
   However, i have to write this (add a `Some` so it becomes an `Option`) which is annoying.
   
   ```rust
   let value_data: Int8Array = [10_i8, 11, 12, 13, 14, 15, 16, 17]
     .into_iter()
     .map(Some)
     .collect();
   ```
   
   Note you can write this, but that is not as idomatic
   ```rust
           let value_data = Int8Array::from_iter_values([10_i8, 11, 12, 13, 14, 15, 16, 17]);
   ```
   
   
   **Describe the solution you'd like**
   But it would be more ergonomic to be able to just use the collect syntax
   
   Namely I want  to write this and have it work:
   
   ```rust
   let value_data: Int8Array = [10_i8, 11, 12, 13, 14, 15, 16, 17]
     .into_iter()
     .collect();
   ```
   
   Also, for BooleanArray and StringArray
   
   **Describe alternatives you've considered**
