Description
### Describe the enhancement requested
Currently, `ParquetFileReader` throws `RuntimeExceptions` when footer parsing fails.
This can be improved by throwing a `ParquetDecodingException` when footer parsing fails, so footer corruption surfaces as a typed exception instead of a plain `RuntimeException`. This helps avoid matching on error message to catch errors occurred during footer parsing.
