Compatibility with LangChain 0.2.0

[Byczong]

I would like to use ragatouille with langchain 0.2.0 (released 3 days ago).

When I try to install ragatouille using poetry in an environment already containing langchain 0.2.0, I get this:

Because ragatouille (0.0.8.post2) depends on langchain (>=0.1.0,<0.2.0)
 and no versions of ragatouille match >0.0.8.post2,<0.0.9, ragatouille (>=0.0.8.post2,<0.0.9) requires langchain (>=0.1.0,<0.2.0).

Right now, in ragatouille's pyproject.toml there are these version specifications:

langchain_core = "^0.1.4"
langchain = "^0.1.0"

I don't know if the langchain update will require serious changes or it will be straigthforward, but I'm looking forward to it!

Thanks for your attention!

@bclavie did you have the possibility to look into this? :)

Oof I'd completely missed this! I'm a bit swamped the next couple days but I'll definitely figure out compatibility fix for both this llamaindex either this week or next week, thanks for tagging me.
