Allow non offset based timezones

Describe the bug

I was trying to make PyIceberg rely solely on Iceberg-rust for the partition transforms, but I ran into the following:

    def _transform(array: "ArrayLike") -> "ArrayLike":
        if isinstance(array, pa.Array):
            return transform_func(array, *args)
        elif isinstance(array, pa.ChunkedArray):
            result_chunks = []
            for arr in array.iterchunks():
>               result_chunks.append(transform_func(arr, *args))
E               ValueError: Unexpected => Parser error: Invalid timezone "UTC": only offset based timezones supported without chrono-tz feature

We initialize the datetime as:

datetime(2023, 12, 31, 0, 0, 0, tzinfo=timezone.utc)

To Reproduce

In test_transform.py:

def test_year_transform_datetime():
    arr = pa.array([
        datetime(1970, 1, 1, 0, 0, 0, tzinfo=timezone.utc),
        datetime(2000, 1, 1, 0, 0, 0, tzinfo=timezone.utc)
    ])
    result = transform.year(arr)
    expected = pa.array([0, 30], type=pa.int32())
    assert result == expected

Expected behavior

Able to just parse these. I'm not sure if we need to fix this in Arrow, or if we can import chrono-tz package.

Willingness to contribute

I cannot contribute a fix for this bug at this time

Seems this is cause by arrow, see https://github.com/apache/arrow-rs/blob/d5339f31a60a4bd8a4256e7120fe32603249d88e/Cargo.toml#L98C51-L98C56 .

The temporal transforms are using arrow to do the transform:

let array = date_part(&input, DatePart::Year)
