Add scripts/sns/find-failed-neurons

[dskloetd]

Motivation

A while ago there was a bug where we didn't enforce the minimum neuron stake for SNS neurons in the UI.
This caused some people to transfer tokens to a governance canister subaccount, after which they couldn't create a neuron because the stake wasn't enough.

At the time I created a script to find such transactions that didn't turn into neurons to get an idea of the magnitude of the problem. I never got around to adding the script to the repo but this is that.

Changes

1. Add helper script scripts/get-transactions which gets a range of transactions from index and archive canisters.
2. Add scripts/sns/find-failed-neurons which based on a date range and SNS looks for staking transactions that didn't result in a neuron. Outputs the amount and a link to the account on the dashboard.

Tests
