Adds Seek and Prev to Iterator interface #11

Closed bbengfort closed 2 years ago

bbengfort commented 2 years ago

Although primarily a leveldb iterator interface, having Prev in addition to Next is going to be a helpful utility if we can implement it with other engines. The larger requirement is Seek which is absolutely needed for pagination and other advanced iteration. These are primarily a passthrough for leveldb operations, but I've also added some tests for the empty iterator which is not a passthrough.
