Add scripts/find-transaction-from-timestamp

[dskloetd]

Motivation

I created these scripts when debugging an issue.
Perhaps they'll be useful again in the future.

Changes

1. Add scripts/get-transaction which lets you get a transaction, taking care of getting it from an archive canister if necessary.
2. Add scripts/find-transaction-from-timestamp which binary searches transactions for a specific timestamp and outputs the transaction index.

Tests

Tested manually:

$ scripts/find-transaction-from-timestamp --network mainnet --ledger_canister_id oj6if-riaaa-aaaaq-aaeha-cai --timestamp 1738364400
