add support for P2SH and bech32 for Litecoin

[mehranj73]

Please add support for P2SH and bech32 address types for Litecoin. I wish I had the knowledge to do so. Maybe you can use this.

P2SH:

val key = ECKey.fromPrivate(BigInteger("12"))
val redeemScript: Script = ScriptBuilder.createP2WPKHOutputScript(key)
val script = ScriptBuilder.createP2SHOutputScript(redeemScript)
val scriptHash = ScriptPattern.extractHashFromP2SH(script)
LegacyAddress.fromScriptHash(params, scriptHash).toString()

bech32: SegwitAddress.fromKey(params, key).toString()

All address types:
