Support ggmlv3

[jingsam]

I download llama-7b.ggmlv3.q4_0.bin from https://huggingface.co/TheBloke/LLaMa-7B-GGML/tree/main, LlamaChat says not a valid model. It seems not support ggmlv3 format.

LlamaChat v2 is coming with expanded support for ggml and other models. development has stalled for a bit but hopefully I'll be able to get back to it soon 👌🏼

@alexrozanski Looking forward to new version.
BTW, as a kind reminder, llama.cpp will have breaking changes on its model format (ggjt-v3 to gguf).
Maybe it is good to keep an eye on this: ggml-org/llama.cpp#2398
