feat: add reverse transformation support

[jptosso]

I found this interesting use case, when payloads are being reversed to avoid detection. t:reverse will help to detect them.

LGTM.

Could you please link any documentation where this is being used or requested?

@jptosso Can this be documented somewhere? Looks like this is now in code only, and this is a new transformation that is not available "upstream".

An issue will also help others determine the use case and if matches their needs.
