GPU Hive delimited text reader does not currently support escape characters.

The default Hive delimited text escape character is '\'. This would allow special characters to be escaped, so as not to be interpreted during parsing.
E.g. "\\N" would be interpreted as "\N" instead of null.

This stems from the implementation of GpuHiveTableScanExec depending on CUDF's CSV Reader, which does not support escape characters (AFAICT).

Depends on rapidsai/cudf#11984.
