Optimise ext table dumping
The original algorithm first grouped ops in a commit by ext engine
type via folding over the list with orddict:append/3, that resulted in
an O(n^2) algorithm.
However, grouping the ops is not needed, the ops can be dispatched to
insert_op/6 one-by-one, after looking up the storage semantics of
their respective engine. This is a much cheaper algorithm, assuming
looking up the storage semantics is cheap (which should be).
