Auth with Amazon account

[dj0174084]

I ran into an undocumented issue which I thought was worth sharing. The auth doesn't work if you used your amazon account to create your eero account. In order to fix this, I added a new network admin which gives you a QR code. Then I signed out of my amazon account in the app and created a new account with my phone/email. Then I used the QR code to get access to my existing network. So now I have 2 admin accounts (eero & amazon) with admin access to my network but the eero account now lets me auth via the script. Works great now. Thanks!

Thanks. Do you want to update the Readme.md file with the new steps? I can accept a PR.

Otherwise i'll keep this open and update it at a later point.
