Named tuples were never really adequate for this since the order aspect of them doesn't make sense.
Further, named tuples don't support multiple inheritance. This meant that the objects returned by get_items() were not actually Items, for example. Since Python 3.9, such named tuples cannot be created anymore.
Fixes#111
VK doesn't always return posts in chronological order, so that can't be used to filter out duplicates. Instead, remember the last 1k post IDs and filter using that. This should catch the vast majority of duplicates. (Also, duplicates can't only happen in the geoblocking workaround; sometimes, VK also simply returns the same post again for no obvious reason.)
To get around the block, try to iterate over post offsets individually instead of in 10-steps. This means we should get every post that isn't blocked as long as there are at least 10 posts between two blocked ones.

Backwards incompatibility: snscrape.modules.twitter.Account is now called User. However, this was previously only used on the list member scraper, which has been broken for a while since the list member list is no longer publicly accessible.
For compatibility reasons, the CLI does not output the entity by default; the new option --with-entity enables it.
