add support for P2SH and bech32 for Litecoin

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](https://github.com/pokkst/litecoinj).

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:
```
