oggz-rip included in liboggz can do this, extract a particular stream
from an Ogg container. My currently installed version of 1.1.1 wont
recognise Opus by content type, though it would be happy detecting
Theora. Either stream could be extracted based on index or
serialnumber.

VLC I think can also copy a component from one container into another.
It may remux in doing so.

What are you ultimately trying to do? Ogg is a container and Opus in
it is perfectly valid and probably going to be increasingly common.
