fix: fix DataFrame.from_records with data as an iterator

[terencehonles]

• Tests added: Please use assert_type() to assert the type of any return value

Hi @terencehonles , thank you for the proposal. However, according to the Pandas documentation, the data parameter in DataFrame.from_records accepts Sequences, not Iterables. Could you please raise an Issue or Pull Request in pandas-dev/pandas regarding the documentation?

I'm not sure if I have time to follow up right now. I opened this PR because mypy is now complaining about some existing code I have (which I have silenced with an ignore statement). This is the pandas implementation and it does handle an iterator https://github.com/pandas-dev/pandas/blob/f6fa9b679006d08fa99d8c2b6dbd834ec60875d6/pandas/core/frame.py#L2240-L2263.

@terencehonles the docs are updated, so now @cmp0xff can review this PR and provide any feedback

The changes are now in accordance with the Pandas documentation.

One minor comment: the idea in L4702-L4711 seems to be duplicated by the code snippet below. Could you remove the latter? Thanks.
