Meant SNS instead of SQS?

Suggested change

	class SqsMsgAttributeModel(BaseModel):
	class SnsMsgAttributeModel(BaseModel):

[ran-isenberg]

fixed!

[heitorlessa]

It looks good to me except FIFO if we want to be future proof

[heitorlessa]

We need groupId and dedupId optional fields that might be added when FIFO is enabled - Haven't tried yet myself.

Publisher reference: https://docs.aws.amazon.com/sns/latest/dg/fifo-topic-code-examples.html#fifo-topic-java-publish

[heitorlessa]

Resolving it as @risenberg-cyberark confirmed Lambda cannot directly subscribe to SNS FIFO topics, it'd have to go through SQS FIFO, in which case our model already covers it.

Thanks for adding support to SNS @risenberg-cyberark :) much appreciated. Merging it now
