Give a way to return the currency related to a locale

[rocboronat]

As this project has a lot of information about the currencies, it would be great to use it to retrieve the Currency related to a given Locale.

@rocboronat The package dose not have this info. Can you provide a valid source?

[rocboronat]

Honestly? Nope... But we could do it for the most used Locales.

For example:

• es_ES fr_FR = Euro
• en_US = US dollar

If we make a long enough list, it will do the job.

I needed this as well and stumbled across this StackOverflow thread.

We can use the intl package to get the currency from the locale; currencyName is equivalent to Currency#code of this package. So you could do something like:

String currencyCode = NumberFormat.simpleCurrency(locale: locale).currencyName;
Currency? currency = CurrencyService().findByCode(currencyCode);

It's quite simple to just do this manually since the currency service is public. I don't think it's worth introducing a dependency just to do this, but if people think it's a good idea I'm happy to raise a PR!
