Сделай жёсткий рефакторинг кода, в том числе:
1. функция ner() очень тяжелая, поэтому некрасиво сначала читать все варианты текста а потом по ним работать. Сделай так что бы сразу иттерировалась база данных, а внутри нее уже с помощью указателя бери строки по кругу из файла food_requests (Food_requests содержит на порядки меньше элементов поэтому нужно по кругу)
2. Обьедини функции ss и bs, сохранив оригинальный алгоритм, просто в этот раз передавай bs как параметр
3. Не забудь про верхнеуровневый tqdm
4. Сохрани оригинальные названия переменных и постарайся не писать новый код, а изменять текущий
