This uses the size hint value from the underlying `slice::Iter`. The iterator itself does not track the symbol count so this slice iter provides the most accurate value

Changes the size_hint() implementation in the archive symbol iterator to use the '..' syntax for unused fields

This PR adds a
.size_hint()implementation to theArchiveSymbolIterator.The value returned for this is the size hint value of the underlying
slice::Iter. This provides the most accurate size hint without needing to add additional fields for keeping track of the iterator's state.I have been working on a project where it would be nice to pre-allocate collections based on the number of symbols inside an archive's symbol map. The default
.size_hint()implementation returns 0 and there is no API in this library that will get this value.
