create ... () parse a cookie instance t from given value parameters. If the given values parses successfully, then Ok t is returned. If an error is encountered while parsing then an Error err is returned.

~sanitize_value if true then value is double quoted if it starts or ends in a ' '(space) or a ','(comma) character.

~sanitize_name if true and name contains '\n' or '\r' character then it is replaced by '-' character.
