Adds Sectioning and Partitioning to jsontable in order to support storing Rows together on disk by shared id prefixes to promote scalability of benchtop storage past single GB per table sizes.
Operations before that would be forced to search the entire table can be more granular, only being needed on certain sections / partitions.
running on cbds development for ~ a month now.
This PR is getting more into deep database design -- Performance improvements are not easy to get anymore, reliability and resilience is what his DB driver needs more of. It's kindof unclear if some of the changes in this PR are better than the previous versions --
