Subject: [PATCH] Change `enum rb_parser_ary_data_type` default value to 1 for
 easy debug

We face `[BUG] unexpected rb_parser_ary_data_type (0) for script lines`
on master branch recently.
This commit changes `enum rb_parser_ary_data_type` to start with `1`
and `0` to be invalid then it makes clear `rb_parser_ary_data_type (0)`
is not intentional.
