other optional params used in scidb::scidbconnect
A boolean value that determines whether to save
the connection object as the default in the arrayop package scope so that
it can be retrieved anywhere using get_default_connection.
In rare cases should we need to maintain multiple connection objects, we can
set save_to_default_conn to FALSE.
Whether to save token/password. Default FALSE. Do not set to TRUE in production env.
A connection object returned by scidb::scidbconnect.
If NULL (NULL), username, token, host, ... params must be provided.

and use the connection object directly
