more than 3 digit currency codes

[JamborJan]

Description
The import extension crypto-trades-firefly-iii allows to import transactions from Binance. Therefore it is required to add all currencies in firefly-iii. Right now firefly allows only 3 digit currency codes which are not enough for cryptocurrencies e.g. AAVE BETH COTI LINK IOTA etc.

Solution
It should be possible to have more than 3 digit currency codes. I'm not aware of any standard here. making it only 4 would also not be sufficient. There are things out there like OCEAN etc.

What are alternatives?
Firefly III and the extension are not usable for all currencies out there.

ISO 4217.

Thanks for that hint. I guess that's rather for fiat currencies and not for cryptocurrencies, right? I don't see any of the cryptocurrencies which are in the default list of firefly-iii in ISO-4217 either. I did a quick check and as far as I can tell, there is no real standard for cryptocurrency symbols (aka codes).

I can extend the option to five or even seven letters, but it'll be a few versions before this will be implemented.

Thanks a lot @JC5. And thanks also for the great work you are doing. Much appreciated.
