Request: normalization and depythonize

[jamesbraza]

When upgrading pythonize from version 0.21.0 to version 0.23.0 in tantivy-py's quickwit-oss/tantivy-py#401, we switched from extract to extract_bound (per PyO3/pyo3#3916).

Now, we are hitting an issue where I64 values are becoming U64 after depythonize.

I came up with a solution in jamesbraza/tantivy-py#1 that involves re-casting U64 back to I64 if it fits, but this is pretty hacky.

Is there some way to preserve integer types across serialization/deserialization?

• I64 values remaining I64
• U64 values remaining U64

I am wondering if there is some way pythonize can accommodate this, maybe by adding an opt-in flag somewhere?

Also, I am not 100% sure if this is a pythonize vs pyo3 issue, but it seems to be a deserialization issue, so I opened this here.
