Custom class that encapsulates a :tl:`MessageFwdHeader` providing an
abstraction to easily access information like the original sender.
Remember that this class implements `ChatGetter
<telethon.tl.custom.chatgetter.ChatGetter>` and `SenderGetter
<telethon.tl.custom.sendergetter.SenderGetter>` which means you
have access to all their sender and chat properties and methods.

original_fwd (:tl:`MessageFwdHeader`):
The original :tl:`MessageFwdHeader` instance.
Any other attribute:
Attributes not described here are the same as those available
in the original :tl:`MessageFwdHeader`.
