Function read_buffer_typed 

pub fn read_buffer_typed<T: Pod>(
    device: &Device,
    queue: &Queue,
    source: &Buffer,
    count: usize,
) -> Result<Vec<T>>

Read back a GPU buffer and reinterpret as a typed slice.

Convenience wrapper around read_buffer that casts the raw bytes to &[T] via bytemuck. The buffer size must be a multiple of size_of::<T>().
