Remove frame unwrapping and WFM code

[nvaytet]

This code is moving to essreduce: see scipp/essreduce#163

Don't know if we want to keep the fakes. Right now they were only used in the unwrap/wfm tests which are gone.

I think they can be removed? Where they also added in essreduce?

Not exactly. The FakeBeamlineEss was moved over, but not the FakeBeamline you initially created. Also, the choppers were not moved, I made some new ones which are using DiskChopper instead of tof.chopper_cascade.Chopper.

[SimonHeybrock]

Do I understand correctly that your last commit does remove them now?

[nvaytet]

Yes, I removed them.
I'm of the opinion that it's ok to remove, but I thought we could revert if you prefered to keep them.

[nvaytet]

I think I forgot to remove the dependency on tof...
