Added some pushdown supports and fixed some critical issues.

  1. Fixed an issue that occurred when writing a DataFrame with Map type column if the name of the column contains spaces.
  2. Fixed an issue that occurred when writing to a table with overwrite mode if the schema name isn't specified as part of the table name, the table is not in the schema specified by the “sfSchema” option, and the PUBLIC schema contains a table with the same name.
  3. Added pushdown support for the COALESCE() function when reading from the Snowflake database.
  4. Added pushdown support for the windows functions of RANK() and DENSE_RANK() when reading from the Snowflake database.
  5. Updated the connector to use the latest version of the Snowflake JDBC Driver (3.12.17).
  6. Updated the connector to use the latest version of the Snowflake Ingest SDK (0.10.1).
