Publishing an official NPM package

I have no current plans to do this, but it is likely that in the future OpenAI will provide an official package. Discuss at #22

Publishing an official Rust crate

In the future when I have time, I will publish the core BPE logic as its own crate. Discuss at #24

I'm short on time currently, but in the longer term I want to explore ways to make maintaining downstream bindings easier. Apologies to the people who've reached out about this — y'all are great, sorry for being a bottleneck.

Packaging

Issues with pyinstaller

I've never used pyinstaller, but people report --hidden-import=tiktoken_ext.openai_public --hidden-import=tiktoken_ext helps make things work. See #43 for more details.

Wheels for other platforms

I'm reluctant to publish wheels for additional platforms, particularly if I can't easily build or test code for them. I'm unlikely to do this unless there's significant interest. Please add reactions to the following issues if you'd like to see those wheels. No promises, but I'll reopen any issue that gets >10 reactions.
