casper-db-utilsto make it compatible with the changed in casper-node 2.0 Condor.In fact,
casper-db-utilsnow doesn't depend on the node and performs most of its operations by using the interfaces provided by thecasper-storagecrate.Some of the direct LMDB access was removed in favour of using
casper-storageinterfaces (since technically the LMDB database can be replaced at any time with a different db), however for low level subcommands likecheckthe tool still opens the LMDB database directly and tries to deserialize entries (either through bincode or bytesrepr depending on weather the database in versioned or not).Fixes: #44
