  1. Python: Remove imprecise container steps 

    - remove `tupleStoreStep` and `dictStoreStep` from `containerStep`
   These are imprecise compared to the content being precise.
- add implicit reads to recover taint at sinks
- add implicit read steps for decoders
  to supplement the `AdditionalTaintStep`
  that now only covers when the full container is tainted.
