Google pay - capture email

[shokimble]

Proposed changes

You can now supply email_required true to paymentRequestWithAndroidPay and email address will be added to extra.shippingAddress and extra.billingAddress in line with Apple pay.

Replaces: #279 which was out of date

Checklist

Put an x in the boxes that apply. You can also fill these out after creating the PR. If you're unsure about any of them, don't hesitate to ask. We're here to help! Next steps are a reminder of what we are going to look at before merging your code.

• I have added tests that prove my fix is useful or that my feature works
• I have added necessary documentation (if appropriate)
• I know that my PR will be merged only if it has tests and they pass

N/A to all - there's no tests that I know of and the docs are duplicated in three different places. I don't know which ones I am updating. Are they auto-generated somehow? Happy to add if I can be pointed to where.

Further comments

Simple change. Have introduced the option to request email or not which defaults to false and placed email in the shipping and billing fields instead of on its own to bring in line with IOS.

@cybergrind cheers for the merge. It helps me as much as anyone as I don't have to worry about my long out of date fork any longer 😋

@shokimble that's why I believe merging your changes to master repository worths most of the efforts of it - someone else is going to maintain it =)
