I encountered an error while processing multi-column PDFs using the pymupdf4llm library. The error occurs in the helpers/multi_column.py file, specifically at line 254. Here is the traceback:
Traceback (most recent call last):

line0 = b["lines"][0] # get first line
IndexError: list index out of range
The problematic line is:
line0 = b["lines"][0] # get first line
This line can throw an IndexError when b["lines"] is an empty list. Could you please modify the code to handle this situation gracefully?
