typo bug when running llama cpp server

[MicDonald]

I believe there's a typo bug in v0.2.87:

File "/home/mkychsu/pool/.conda/envs/LLM2/lib/python3.10/site-packages/llama_cpp/llama.py", line 2163
for file in hffs.ls(repo_id, recursive=True))

Thank you for your efforts in bringing llama.cpp alive to python world!
