Robustly bump dependency versions

[jaketae]

In light of #74, this PR flexibly bumps project dependency versions by replacing hardcoded == version requirements with >=. This will allow pip to install the latest versions when possible and also resolve the test CI error.

Additionally,

• The unnecessary tensorflow dependency is removed
• Dependencies are re-ordered to give priority to torch and transformers

@tianjianjiang, can you help update poetry.lock and pyproject.toml files? I think the test CI currently works off of setup.py, which reads from requirements.txt, but I think it's also a good idea to keep other files consistent if we update requirements.txt. Thank you!

Looks good to me!

@jaketae Roger that!
