* Refactor Chinese tokenizer configuration Refactor `ChineseTokenizer` configuration so that it uses a single `segmenter` setting to choose between character segmentation, jieba, and pkuseg. * replace `use_jieba`, `use_pkuseg`, `require_pkuseg` with the setting `segmenter` with the supported values: `char`, `jieba`, `pkuseg` * make the default segmenter plain character segmentation `char` (no additional libraries required) * Fix Chinese serialization test to use char default * Warn if attempting to customize other segmenter Add a warning if `Chinese.pkuseg_update_user_dict` is called when another segmenter is selected.
