[cuda/gg_ttgg] Use conservative unweight fudge factor

hageboeck · hageboeck · commit b6573ad66575 · 2023-04-14T15:11:03.000+02:00
Now that the max event weight can be computed in each batch, the
unweight fudge factor for accepting / rejecting an event can be chosen
much closer to one. Here we go on the conservative side, where we accept
about twice as many events than go to the final sample.
