### Describe the bug, including details regarding any error messages, version, and platform. When a column is dictionary encoded but the type doesn't exist as a typed dictionary encoder, the columns writer panics. To reproduce: run [this test](https://github.com/apache/arrow-go/blob/3c01efba60abe1421a49ac21c95858dbfccd78d6/parquet/pqarrow/encode_dictionary_test.go#L70-L111) with `arrow.PrimitiveTypes.Uint8` and observe a panic resulting from [this](https://github.com/apache/arrow-go/blob/3c01efba60abe1421a49ac21c95858dbfccd78d6/parquet/internal/encoding/typed_encoder.go#L165) type assertion. The underlying cause, in this specific case, is because the underlying type is `uint8` but the encoder is `int32` ### Component(s) Parquet -- This is an automated message from the Apache Git Service.
