Amounts information is not present in transactions when parsing CAMT.053

[omerhayatgill]

In CAMT.053 parsing, Transaction interface has instructedAmount and instructedCurrency fields but they are not populated by the parser.
Apart from instructed amount and currency, we also should add visibility of actual amount and currency which are always present.

Sounds like a great idea for a fix @omerhayatgill - we should make sure we handle "nullable" if instructed amount / instructed currency don't exist. I'd have to check the spec (which is in the repo) to double check.

Seems like we have two tasks ahead of us:

• We need to populate instructedAmount and instructedCurrency
• We need to populate amount and currency

A sample CAMT file (with information obfuscated out ofc) would be really helpful here so we can validate our files are processed correctly
