Use algorand indexer to retrieve past transactions

[stefanofa]

Given the current throughput of Algorand, users are unable to redeem transactions that were made more than approximately 55 minutes ago. This limitation arises from the use of the pendingTransactionInformation endpoint in the Algorand client, which only supports requests for transactions up to 1000 blocks in the past. To retrieve any transaction beyond this limit, we need to utilize the Algorand indexer.

To solve this problem, I made the necessary request via the indexer. However, the transaction encoding differs between the two endpoints, so I performed a transformation of the latter to make it compatible with the parameter required by parseSequenceFromLogAlgorand.

Tried it out locally and managed to start the recovery for an old tx, while the main branch version would fail with a 404.

I only have a small nitpick for parsing only the first inner tx's log instead of all, but the wh sdk only expects the first one. But we can take care of that later.

Thanks for the PR @stefanofa!
