Part 2: Use value_and_span apparatus in tx-parser/.
I break an abstraction boundary by returning a value column `edn::ValueAndSpan` rather than just an `edn::Value`. That is, the transaction processor shouldn't care where the `edn::Value` it is processing arose -- even we care to track that information we should bake it into the `Entity` type. We do this because we need to dynamically parse the value column to support nested maps, and parsing requires a full `edn::ValueAndSpan`. Alternately, we could cheat and fake the spans when parsing nested maps, but that's potentially expensive.
