Zimscraperlib

Added

- `zim.Creator` now supports `ignore_duplicates: bool` parameter to
prevent duplicates from raising exceptions

now supports a `duplicate_ok: bool` parameter to prevent an exception
should this item/redirect be a duplicate

Added

- `download.stream_file()` supports passing `headers` (scrapers were already using it)

Changed

- Fixed `filesystem.get_content_mimetype()` crashing on non-guessable byte stream

Changed

- Wider range of accepted lxml dependency version as 4.9.1 fixes a security issue

Added

- `Archive.get_metadata_item()` to retrieve full item instead of just value

Changed

- Using pylibzim v1.1.0 (using libzim 7.2.1)

Changed

- `zim.Archive.article_counter` follows libkiwix's new bahavior of
