Adjust the “child only” idno configuration so that if a level is skipped in the creation of a record hierarchy there isn’t a blank section in the indo number. So, for example, a nice consecutive idno span goes from 2019.001 to 2019.001.01 to 2019.001.01.01.
But, if, for example, a sub-series is created directly under a collection it has the idno 2019.001...01.
Intervening blank levels should be filled with 00. So 2019.001..01 would become 2019.001.00.00.01.
