Re: [w3c/payment-method-basic-card] Leave Off Unneeded Information (#5)

Apart from `cardNumber`, the spec makes members optional... if the user chooses not to include some member's details, then they are just set to the empty string. 

However, certain user agents force the user to enter all credit card information before they can proceed... but all user agents allow the user to abort the payment process. 

Now, just the first 6 digits of the card number can reveal about a user (using https://www.bindb.com): 

- Card Brand: 
- Issuing Bank: 
- Card Type: 
- Card Level: 
- Iso Country Name: 
- Iso Country A2: 
- Iso Country A3: 
- Iso Country Number: 
- Bank's website: 
- Customer Care Line:
- Bank Address:
- Formal Bank:
- Commercial/Personal Card:
- Additional Info:

@adamroach, do you think we should make some kind of mention of the above?
