Is your feature request related to a problem or challenge? Please describe what you are trying to do.

Currently PageIndex, while similar to Statistics, doesn't support max_bytes and min_bytes.

Describe the solution you'd like

Add max_bytes and min_bytes to PageIndex<T> where T: AsBytes.

Describe alternatives you've considered

Additional context

There was some discussion of this w.r.t. this ticket: apache/datafusion#10951 because f16's physical type is a fixed len binary array. Ultimately the better solution is for parquet to natively support f16 that may take longer and be more involved when it's implemented.

label_issue.py automatically added labels {'parquet'} from #5950
