Support more numerical types

I tried to use lsdb-server to filter a uint16 column (magerr in zubercal), but it is not supported yet:
```
thread 'tokio-runtime-worker' panicked at /astro/users/dtj1s/code/lsdb-server/src/loaders/parquet/parquet.rs:94:15:
called `Result::unwrap()` on an `Err` value: NotYetImplemented("Data type UInt16 not yet implemented")
```
