fix: use updated ISO-4217 for currencies

[svn-arc]

The library currently being used for the list of currencies js-money is out of date. i.e., it uses an outdated currency code for Zambian Kwacha (ZMK) and Belarusian Ruble (BYR). This makes it impossible to select either currency as the base currency on the web app. We get a validation error.

There is a pull request on the library, but it's been pending for 6 years.

This PR:

1. Removes out of circulation currencies (EEK,LTL,LVL)
2. Changes currency codes (BYR to BYN, ZMK to ZMW)

@svn-arc check out this issue for more currency related issues. Perhaps you can include those currencies as well and fix more issues with this PR: #724
