Adds option to provide an OpenAI project id

[amokan]

Given that the library already supports the OpenAI-Organization header, it made sense to give similar treatment for the OpenAI-Project header as outlined here.

I am open to any feedback or changes you'd prefer. Just let me know!

Thank you for the library @restlessronin !

@amokan thanks for the PR.

Just out of curiosity, are you adding this because you have a use-case that it is needed for, or because it's mentioned in the documentation but not implemented?

I had noticed it a few months ago, but from the documentation it seemed like the PROJECT_API_KEY could be used directly as a token, and this was more of a backward compatibility feature. I decided at the time that I would wait to implement it until someone had an actual need for it.

But it's also fine to implement it because it's a documented feature. I am still curious if it is really needed.

Great question! I apparently did not pay attention to the docs that indicated the backwards compatibility there so I've been using the project header quite a bit.

But I do appreciate the merge 😄
