Support for bc1 addresses (Bech32)

[bsubasic]

It seems that the converter doesn't support the new BTC address format that starts with bc1 and is usually longer in length.

example:

37XuVSEpWW4trkfmvWzegTHQt7BdktSKUs (older format)
bc1qgdjqv0av3q56jvd82tkdjpy7gdp9ut8tlqmgrpmv24sq90ecnvqqjwvw97 (new format)

This is the error when it tries to convert it:

Traceback (most recent call last):
  File "D:\btcposbal2csv\convert2ripemd160.py", line 41, in <module>
    process(args.csvin)
  File "D:\btcposbal2csv\convert2ripemd160.py", line 19, in process
    ripemd_bin = tocondensed(row.split(',')[0])

Hello,
thanks for pointing this out. I didn't consider the bech32 addresses when writing this script. I'll look into this when I have free time.

This would be awesome if you can update this. I use this script a few times a year. Thanks for your efforts on this by the way.

Hi, there is an RPC in reference blockchain which, when merged would replace much of this library functionality. I'm waiting to see what it's fate will be and then I will decide if to incorporate the bc1 addresses.

I have PRed changes to support bech32 addresses here: #34, in event you are still in search of a solution.
