Support iterators

[rgaudin]

Archive needs support for a few iterators:

• Archive.iterByPath()
• Archive.iterByTitle()
• Archive.iterEfficient() (arguable)
• Archive.findByPath(path)
• Archive.findByTitle(title)

Awaiting this to remove Archive.get_entry_by_id(), Entry.index and Item.index as it's the only way to loop over the zim content at the moment and we use it in tests.

It would be nice to have a "default" iterator (iterEfficient?) on Archive itself.

This way we could iterate over archive with :

archive = Archive("foo.zim")
for entry in archive:
    print(entry.title)

absolutely 👍
