By casting the read record batch to the delta schema datafusion can read tables where the underlying parquet files can be cast to the desired schema.

Description
When creating the ParquetExec plan in DeltaScanBuilder. The parquet options on the ParquetExec are left with their default values. This PR uses the SessionState on the builder to clone the ParquetOptions from.
This allows you to create your SessionContext/SessionState with additional Parquet reader options enabled (row filter pushdown, page index, rog group bloom filter pruning, etc).
