Litecoin RPC GetBlock() throws System.FormatException: Unknown Transaction optional data for some blocks

[rvnlord]

There is a bug with Litecoin serializer which will throw System.FormatException: Unknown Transaction optional data for some transactions in some blocks. To reproduce run:

var customHash = (await Rpc.GetBlockHeaderAsync(2284382)).GetHash();
var block = await Rpc.GetBlockAsync(customHash);

or

var resp = await Rpc.SendCommandAsync(RPCOperations.getblock, CancellationToken.None, customHash, false);
var block2 = Network.Main.Consensus.ConsensusFactory.CreateBlock();
var s = new BitcoinStream(new MemoryStream(Encoders.Hex.DecodeData(resp.ResultString)), false) { ConsensusFactory = Network.Main.Consensus.ConsensusFactory };
block2.ReadWrite(s);

Example transaction that causes the problem can be found in block 2284382 with 3bed06209f382e20f7b4eb1724366835874769763744d3cc429182422c8e7950 hash.

@rvnlord can you copy the transaction's hex here?

Should be fixed #1125 was caused by a hardfork of ltc
