[bug fix] objectType should work w/ or wo/ ENABLE_STRUCTURED_TYPES_IN_CLIENT_RESPONSE

[madisonchamberlain]

Description

If we get a snowflake object type, but we haven't set the flag ENABLE_STRUCTURED_TYPES_IN_CLIENT_RESPONSE, the code will panic because we are only setting the record on the batch if the snowflake type matches the expected arrow type. This will add support for the underlying type to be either structured or string for snowflake objectType, and if its neither, we will return an error with the underlying type rather than panic so we can fix it

Checklist

• [X] Created tests which fail without the change (if possible)
  • TestStructuredTypeInArrowBatchesWithoutEnablingStructureTypes: check that we can have an object type without setting structured types flag
  • TestNullObject: ensure that we can have a null object. (This is what was failing in my test suite; ultimately this isn't the actual trigger of the panic, but its still good to test because it could be one day)
• [NA] Extended the README / documentation, if necessary

I cant get this to correctly rebase off my fork so I moved it all here https://github.com/snowflakedb/gosnowflake/pull/1137
