feat: permit owned iteration over entries

[sftse]

We needed an EntryHandle that owned its reader. This required a fork of rc-zip-sync but it isn't clear if we want to go through the process of upstreaming that patch just yet.

A prerequisite for this is owning the iterator over the entries, so this is the small modification we had to do to rc-zip itself.

looks good to me! im definitely interested in exploring an an owned EntryHandle (there's been a few open PRs for it, just been busy 😮‍💨)
