[GitHub] [arrow-rs] tustvold opened a new issue, #3929: Strongly Typed Array Slicing

   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**

   (This section helps Arrow developers understand the context and *why* for this feature, in addition to  the *what*)
   -->
   
   Currently calling `Array::slice` returns an `ArrayRef`, even if calling on a strongly typed array. This results in a lot of code of the form
   
   ```
   let a = Int32Array::from(vec![Some(15), None, Some(9), Some(8), None]);
   let a = a.slice(1, 4);
   let a = a.as_primitive();
   ```
   
   This is not only verbose but has potential performance implications.
   
   **Describe the solution you'd like**
   <!--
   A clear and concise description of what you want to happen.
   -->
   
   Arrays should provide `Array::slice(&self, offset: usize, len: usize) -> Self`
   
   **Describe alternatives you've considered**
   <!--
   A clear and concise description of any alternative solutions or features you've considered.
