Cannot read parquet file that was generated from nanoparquet

[RealTYPICAL]

Describe the bug, including details regarding any error messages, version, and platform.

When trying to use MessageColumnIO to get a record reader, the following error occurs:

Exception in thread "main" java.lang.UnsupportedOperationException
	at org.apache.parquet.column.values.ValuesReader.readInteger(ValuesReader.java:178)

I expected that this would work. Pyarrow for example can read the file.
