Add search/split iterators for Python about stringzilla

[ghazariann]

I'm very interested in contributing to this project as my first step into open-source. I believe I could start by addressing this issue. To clarify, are we aiming to replace the Strs type with something like StrIterator that yields strings lazily? As a first step, should I focus on modifying the split function to eliminate the use of realloc and ensure it returns an iterator instead? Any guidance on this would be greatly appreciated.

Hi @ghazariann! I don't think we should replace the Strs. We should keep both. The split should provide an iterator, which should if materialized, is converted to Strs. How does that sound?
