Saves this attachment into a file-like object.
Parameters
----------
fp: Union[:class:`io.BufferedIOBase`, :class:`os.PathLike`]
The file-like object to save this attachment to or the filename
to use. If a filename is passed then a file is created with that
filename and used instead.
seek_begin: :class:`bool`
Whether to seek to the beginning of the file after saving is
successfully done.
use_cached: :class:`bool`
Whether to use :attr:`proxy_url` rather than :attr:`url` when downloading
the attachment. This will allow attachments to be saved after deletion
more often, compared to the regular URL which is generally deleted right
after the message is deleted. Note that this can still fail to download
deleted attachments if too much time has passed and it does not work

--------
