Reindex transactions that had IBC hashes that were translated

[pharr117]

We had implemented IBC hash translation during transaction indexing to translate to the u-denom form. We want to remove this so that the indexed data stays closer to the on-chain data. This will require reindexing many transactions.

The process will look like this:

1. Gather ALL transactions that have a reference in denomination_sent/_received to a non-native Osmosis token
2. Gather the list of blocks
3. Write a reindex process that:
   • Deletes the old data
   • Replaces the old data with the new data
   • Eliminates the IBC hash translation
