ENHANCE: Isomorphism/Automorphism speedups

- Better composition series choice in `SubgroupConditionAbove` -- move known
  parts on bottom
- Improvements in normalizers in `SubgroupConditionAbove`.
  Use NormalizerViaRadical if there is huge radical bit.
- Delay bottom permrep, if bounded orbit algorithms will do the job.
- Allow forcing old isomorphism test
- Redo generators when searching for trick relators
- Require to stabilize sets of normal subgroups (may reduce in factor)
