Support Baichuan2?

[lx0126z]

Baichuan2 is a generative model similar to llama, I find the following two differences:

• 1. qkv merge as W_pack, so i change the file /ctranslate2/converters/transformers.py
• 2. rotary changes to alibi, so i change the file /ctranslate2/converters/transformers.py

But I found that the conversion only worked on simple sentences, complex sentences would not work.

Could you help me or is there a plan to support Baichuan2?
