Support serde for Monzo and YNAB transaction structs
Define transaction structs for both Monzo and YNAB. Each package has a `main`
function that runs some shallow but preliminary round-trip tests for the
serializers and decoders.

The fixtures.json file that each of them is referencing has been ignored in case
either contains confidential data of which I'm unaware.
