Include XVG

Things I need:

• Supported hash functions (Bitcoin derivatives typically include RIPEMD160, SHA1, and SHA256) and a link to the code that supports them
• Transaction malleability fix status (e.g. is SegWit on mainnet) and supporting evidence
• Support for Hashed Time Locked Contracts (typically by supporting OP_CHECKLOCKTIMEVERIFY, introduced in BIP65) and a link to supporting code
• Link to the software implementation that shows XVG in an atomic swap and its current status

@jonathancross yeah, since this issue was opened 2 years ago, we rebased with bitcoin 0.18 (now almost 0.19), so you can definitely go ahead with it now. we do not use segwit.
