Example wallet private key: printf bug?

[wildmolasses]

Hi! As I'm stepping through this project I'm really admiring the work you've done. I may have found a small bug in the example wallet:

kasparov/examples/wallet/create.go

Line 19 in 5cca792

fmt.Printf("Private key (hex):\t%x\n\n", privateKey.Serialize())

It might be the case that privateKey.Serialize() should be printed with %s instead. i.e. fmt.Printf("Private key (hex):\t%s\n\n", privateKey.Serialize()). Something with the underlying byte array I guess.

example with %x:

This is your private key, granting access to all wallet funds. Keep it safe. Use it only when sending Kaspa.
Private key (hex):	 30653434666662646262313565313665653961313830346234613766343162396539326463383038633031623737316235373166303133333562373133356665
