Bitcoin: Convert key hash to Bitcoin address

[jornfranke]

At the moment BitcoinScriptPatternParser returns the key hash which can be used to identify the unique address of a transaction and also to search it in blockchain explorers.
Bitcoin has also the notation of Bitcoin addresses which are primarily for users to improve the user experience. The conversion of such addresses is described in https://github.com/bitcoin/bips/blob/master/bip-0013.mediawiki

The idea of this issue is to create a functionality BitcoinScriptPatternParser.getBitcoinAddress(String) that converts the output of BitcoinScriptPatternParser.getPaymentDestination to a bitcoin address (if possible). Additionally we create HiveUDFs. All new methods need to be unit tested and documentation needs to be updated.

Is there any progress on this issue? If not, then I will be happy to start implementing this.

Ah sorry yes you can implement it, i did not do much there, because there was no urgent need for my analysis
