Add ability to import wallets by private key and/or WIF

[Warchant]

I have a private key which is a 32-bytes hexencoded string. I use it on my internal tools to etch new runes or send them (on testnet4).

Like this:
7f00xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx882d1b8d7e

Please add ability to import a wallet in XVerse via a private key. Maybe only for non-mainnet networks (as a safety measure).

Maybe also import of a WIF-encoded key:

cRqxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxqrcKHnLGpS

This one can be imported to bitcoind with importprivkey.
