Title: Change behaviour when flattening read API output

When given this input:

group_by: type, collect: value:sum, type: elephant

Previously the flat merge would have generated keys of the format

elephant:value:sum: 999

But actually the output which we would find far easier to handle is of the format

type: elephant
value:sum: 999

This commit removes most of the flat merge processing to give us output from the API which is easier for clients to handle.
