Draft: Resolve "RocksDBEmul.removeLiveLevelPair() deletes pair in the wrong order"
Resolves #4
Inverts the order of operation in RocksDBEmul.removeLiveLevelPair()
: first we delete the filename from the manifest, then we delete the file itself. Then implement a garbage collection when we recover that deletes files removed from the manifest and not deleted
