u64::MAX does not roundtrip through parquet

[crepererum]

Describe the bug
u64::MAX gets truncated to 0 when storing to parquet and reading back.

To Reproduce
Add the following test:

#[test]
fn u64_min_max() {
    let values = Arc::new(UInt64Array::from_iter_values(vec![u64::MIN, u64::MAX]));
    one_column_roundtrip("u64_min_max_single_column", values, false);
}

Expected behavior
All values either roundtrip correctly or some error is produced - at least they should not be silently truncated.

Additional context
Tested on commit 8f030db53d9eda901c82db9daf94339fc447d0db.

Some more context: the logical type u64 is stored as the physical "i64 w/o sign bit". As per format specs:

If a stored value is larger than the maximum allowed by the annotation, the behavior is not defined and can be determined by the implementation. Implementations must not write values that are larger than the annotation allows.

so in theory we could map the logical range (i64:MAX as u64)..u64::MAX to the physical range i64:MIN..0i64. From looking at the C++ code I think (!!!) this is also what C++ is doing:

https://github.com/apache/arrow/blob/0ee3b90cac8f8eb3bf512e51a7f941fcead026d9/cpp/src/parquet/arrow/reader_internal.cc#L307-L322

aka: "reinterpret signed as unsigned ints".

Then the only bit that might be tricky (or not in which case a to-be-written test will pass) is to get the statistics right.

BTW: I'm working on that issue.
