Title: Validate MD5 checksums in SQS operations.

This feature can be disabled by passing `computeChecksums: false`
to the SQS service object constructor.

Affected operations are:

* sendMessage
* sendMessageBatch
* receiveMessage

If any messages sent or received in these operations fail the MD5
check, an error will be raised for the affected message.
