Describe the bug

This came up in apache/arrow-datafusion#3783

I believe it is safer choice to infer nullable types always, and the benefit of having non-null inferred is relatively limited.

To Reproduce

Infer csv with nulls that occur after beyond the number of rows schema inference is using.

Expected behavior
