Uninformative Error when context not set in Scallopy

[buddha314]

WIthout the provenenance, this error on tuple size appears with no indication of cause

  ctx = scallopy.ScallopContext()
    
   ctx.add_relation("digit_1", int)
   ctx.add_facts("digit_1", [(random.random(), (i,)) for i in range(4)])

yields

   ctx.add_facts("digit_1", [(random.random(), (i,)) for i in range(4)])
  File "/root/miniconda3/lib/python3.12/site-packages/scallopy/utils/history.py", line 23, in wrapper
    return f(this, *pos_args, **kw_args)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

IndexError: Invalid tuple size

It is correct with this, but that wasn't clear.

  ctx = scallopy.ScallopContext(provenance="topkproofs")
    
  ctx.add_relation("digit_1", int)
  ctx.add_facts("digit_1", [(random.random(), (i,)) for i in range(4)])
