Describe the bug

Since #1682 the parquet reader will ignore the signedness of the embedded arrow schema and always return unsigned integer arrays. This might be a bug in the writer, as it doesn't appear to be setting the ConvertedType/LogicalType

To Reproduce

Attempt to roundtrip an unsigned integer array

Expected behavior

The values should roundtrip correctly
