Add createwallet

[zyo2012]

Can this library be use to handle more than 1 wallet, bitcoin-cli.exe have the createwallet command with a unique id and the connection can have the --rpcwallet with the same id.

What are the alternative if I need to handle more than 1 wallet. Thanks

createwallet needs to be added first in BitcoinLib. (Feel free to send a pull request for it.)

Keep in mind though, this is about creating multiple wallets, each with a separate set of addresses.
