Progressive list

Hi @copilot, could you try implementing an iterator over ProgTree which wraps an iter::Iter instance and keeps track of the next ProgNodes to continue iterating from? The iterator should iterate all elements in the first right child, and then the right child of the first left child, right child of the second left child, and so on. The ProgTree structure is represented by this diagram below:

        root
         /\
        /  \
       /\   1: chunks[0 ..< 1]
      /  \
     /\   4: chunks[1 ..< 5]
    /  \
   /\  16: chunks[5 ..< 21]
  /  \
 0   64: chunks[21 ..< 85]

Hey @copilot, can you try adding ProgressiveList to the proptest suite of tests in src/tests/proptest/operations.rs? You'll need a new ProgressiveSpec data structure that doesn't have a length limit (no N), but you can reuse the same Op structure as we should support all of the same ops eventually (for now their implementations on ProgressiveList can be no-ops if not implemented). You'll want to write a new function apply_ops_progressive_list.

We can probably assemble as we go instead, but I'm not sure how much value that adds
