Conversation
…into analyzer_utils Removes the dependency on these private snowflake-connector-python functions (previously imported from connector.pandas_tools). Ports the implementation from universal-driver PR #518 directly into Snowpark so the connector no longer needs to expose staging helpers as part of its public surface.

Ports the `_create_temp_stage` and `_create_temp_file_format` implementations from the Universal Driver connector (PR snowflake-eng/drivers#518) directly into Snowpark's `analyzer_utils.py`, removing the dependency on these private `snowflake.connector.pandas_tools` symbols.
Changes:
to_pandaswill only convertTimestampTypes to a native pandas date format, and notDateTypes #518), so the caller no longer pre-maps via `compression_map[compression]`.Companion: snowflake-eng/drivers#518 (which implements the same functions in the UD connector for its own `write_pandas` flow — the two implementations are kept in sync).
