Dry material (missing scenarios)

[DariusParvin]

A lot of the notebooks are a bit dry and factual. Some of the notebooks have scenarios that aim to tell more of a story and perhaps illustrate some examples of how a particular type of transaction/feature might be used.

e.g. the notebook on sighash flags tells a story about Jose who creates a signature using a specific sighash flag to give him flexibility over how he spends a UTXO from a wallet he doesn't access often.

For any of the notebooks, if you can think of a scenario (or a better scenario to what's there), please suggest it. PRs are welcome!
