Error; Option to limit the number of items?

Hi,

Thanks for the wonderful plug-in. I ran into this error while trying it on my account.

Is it that my account with 12.3k items is too big to fetch with this?

If that's the case, can you add an option to limit the number of items? (i.e. last k recent items)

Thanks again.

Reproduce the failure with `pocket-to-sqlite fetch pocket.db`, then start at `pocket_to_sqlite/cli.py:101` and follow `utils.py:9` and `utils.py:119`, where the traceback occurs. Determine how the fetch should support selecting a limited number of recent items and how the observed response error should be handled; done means the command works for this account and the limit is honored.
