BitcoinDescriptorChecksum

• Computes the descriptor checksum for public as well as private keys, unlike the bitcoin RPC getdescriptorinfo (bitcoin-core v0.18.0)
• Descriptors containing private keys can be used to derive hardened child keys with the RPC deriveaddresses (e.g. the bitcoin-core keypath m/0'/0'/i')
• For details on the format of a descriptor, see Support for Output Descriptors in Bitcoin Core
• Standalone version of the code found here
