Delete undocumented functions

[yangdanny97]

Found using a script as described in #1253

I did not delete anything in _testing, since I assumed they are test helpers.

Deletion performed automatically using a libCST codemod script: https://gist.github.com/yangdanny97/5d07f14527ac46035208a8119f3cfca2

You're getting some errors. I'm OK if you remove the is_array_like() tests because that's not documented, so we shouldn't have tests for it.

[Dr-Irv]

Thanks for doing this. I found other things you can delete.

For some of the files, there are just whitespace changes - not sure why. E.g., pandas-stubs/io/sas/sasreader.pyi . Not sure why that is happening.

Thanks for the review! I'll clean things up later today or tomorrow

Not sure why there were a bunch of whitespace changes, I thought libCST was supposed to be whitespace-preserving.

CI is showing that deleting pandas-stubs/core/computation/scope.pyi caused issues. You can put it back, and remove ensure_scope() from there. I do think, with some work, some of the things in pandas-stubs/core/computation/pytables.pyi can be removed, but then pandas/io/pytables.pyi has a dependency there so it's a bit painful to untangle.

Maybe we save the trickier part for a separate PR, since this one is already kind of large.

[Dr-Irv]

Well now mypy is happy, but pyright is not. See the CI logs and fix the corresponding issues.

[Dr-Irv]

So I think this is good to go. Feel free to take it out of Draft status and ping for final approve/merge

[yangdanny97]

Cool, ready to go.

Thanks @yangdanny97
