`counts_and_outcomes` for `BubbleSortSwaps` should also accept state space sets

[kahaaga]

Like for SequentialPairDistances, this should just skip the embedding step.

This involves annotating x in the current version of codify(::BubbleSortSwaps, x) such that x is an AbstractVector, and adding an additional method for codify that operates on AbstractStateSpaceSets.

The OutcomeSpace overview table entry should also be updated accordingly.
