## High Level Overview of Change

<!--

If too broad, please consider splitting into multiple PRs.
-->
Handle non standard currency that decoded to 3 characters, putting
prefix `Fake` to such currency.

Instead of being non-standard, 3 character currency codes should use the
[standard
format](https://xrpl.org/docs/references/protocol/data-types/currency-formats#standard-currency-codes)
if they are not "fake".
