Add Qwen1.5 as base model and support adapters about lorax

[tgaddair]

Hey @KrisWongz @thincal, #327 adds support for Qwen2 models. I haven't yet tested the LoRA loading as I haven't found a public LoRA adapter for these models yet, but if you know of one, happy to test it out.

Thanks @thincal, I can definitely take a look to see what has changed in this version and hopefully put together a quick PR, if no one gets to it first.

@tgaddair please help review this request, thanks.

Is qwen1.5 now supported?
An error occurred when running qwen1.5-14b-chat with adapter:

Without adapter can work.

I'll be taking a look at this today. Hope to have a PR up soon!
