Library usage

Loading an SPL Mint

    import "github.com/dfuse-io/solana-go/rpc"

	addr := solana.MustPublicKeyFromBase58("EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v")
	cli := rpc.NewClient("http://api.mainnet-beta.solana.com/rpc")
	acct, err := cli.GetAccountInfo(context.Background(), addr)
	// handle `err`

	var m Mint
	err = struc.Unpack(bytes.NewReader(acct.Value.MustDataToBytes()), &m)
	// handle `err`

	json.NewEncoder(os.Stdout).Encode(m)
	// {"OwnerOption":1,
