grepability: Show balance as SBC, RUSD, Sum

[maurermi]

Instead of this

$ node dist/index.js wallet balance --private-key $PRIVATE_KEY
Address: 0x01A151CC5ED14d110cc0e6b64360913DE9f453F1
Balance: $0.16 ($0.030002 SBC + $0.129961 RUSD)

Consider having each entry on a new line

$ node dist/index.js wallet balance --private-key $PRIVATE_KEY
Address: 0x01A151CC5ED14d110cc0e6b64360913DE9f453F1
SBC: $0.030002
RUSD: $0.129961
Total: $0.16 

This seems to be easier to grep and also will be easier to maintain if we add more assets (USDC). Maybe there is a benefit I'm missing with it being on one line though
