[imbajin]

🚧 WIP status:

• Support Python 3.12 (We need test in different env, currently tested in MacOS ARM), add it in CI env later

Other TODOs moved to #54

[ChenZiHong-Gavin]

Tested Python3.12 on win11, and found the problem.
Versions of tiktoken before 0.5.2 did not build Python3.12 wheels, see main/CHANGELOG.md#v052

RUN pip install tiktoken>=0.5.2
