Add UUID (OID 2950) handling to ParquetFileAccessor by mapping it to BINARY with STRING logical type annotation, consistent with how ORC and JDBC connectors handle UUID. UUIDARRAY is also supported automatically through the existing array type framework.

Will test on weekdays that it works with parquet files from other databases. Probably they encode UUID as 16-byte FIXED_LEN_BYTE_ARRAY primitive type.
