Make HLT runtime validation optional, turn it off in all but the CI-ART tests (mc and data), newJO, and the equiv grid tests

`RecoFragmentsPool.retrieve` hashes its arguments. `DataHandle` is not
hash-able. Work-around by hashing its path.

Add a few explicit `str` conversions for DataHandles.

Fix some formatting warnings seen with python 3.8.

Move ViewCreator* from ViewAlgs to DecisionHandling. Integrate into DecisionHandling/InputMakerForRoI

Details of changes:
- ChainMerging: makeChainSteps function now creates empty sequences when the input step is None. Also removed some commented code.
- MenuComponents: check for consistent number of sequences and chain dicts per step when creating hypos.
- LS2_v1: Add 3 emu chains. Two are primaries, the etcut1step chain is there to test merged chains with different numbers of steps.
