Code Review
This pull request adds support for compiling f-strings, nullity checks (such as 'is None' and 'is not None'), and various string operations (e.g., capitalize, islower, isupper) in Python UDFs. Feedback is provided regarding the Polars compilation of 'IsLowerOp' and 'IsUpperOp', where the current regex patterns incorrectly require the entire string to consist only of letters, failing to match Python's native behavior which allows non-cased characters.

style nit: please add empty lines between the "arange" "act" "assert" blocks to demarcate them, and apply the style to the rest of the changes too.
