Added SES Driver

[mabadir]

Hello,
This PR basically adds SES support to Laravel Mailbox. It is overcoming few shortcomings from Amazon SNS.

1. The POST request from SNS has content-type as text instead of JSON.
2. SNS posts a request first without the Authorization header, and expects a response of 401 Unauthorized and Realm.

Appreciate your review and comments.

Question here: am I correct in thinking that this would not work for emails with attachments? As SNS has a limit of 150 kb for the email size?

Is it possible to merge this pr? Or do you have any idea for amazon ses?

@mabadir is there a fixture for this to make sure the request gets parsed correctly?

Any news on this?

Hi All,
I am not using laravel-mailbox any more, happy for someone else to take on this PR.

Happy to merge this as soon as I get some confirmations of people who test this with SES, since we don't use it.
Also, there's documentation still missing.
