Add exception on logit_bias for gpt-4-turbo (#360)

# PR Checklist
- [ ] Did you check if it works normally in all models? *ignore this
when it dosen't uses models*
- [ ] Did you check if it works normally in all of web, local and node
hosted versions? if it dosen't, did you blocked it in those versions?
- [ ] Did you added a type def?

# Description
As gpt-4-turbo model can both receive logit_bias and inlay image, I make
some exceptions from removing bias on the request.
I check it run well with proxy, but not tested with API key, so testing
with official API is needed before merge.
