Currency codes are flagged as typos

[lokomilo]

Currency code strings such as USD and GBP are flagged as misspellings. Case does not seem to affect this, i.e. usd and gbp are also flagged.

This should be easily fixed by adding currency code strings to the ignore list. Perhaps the list of active codes at https://en.wikipedia.org/wiki/ISO_4217#Active_codes_(list_one) is suitable.

Could be added to the base.stub preset or perhaps a new currency specific one if that is preferred.

@lokomilo Good Idea 👍🏼

On this topic there might be other iso codes we should also whitelist (e.g. countries etc.).
Could you maybe check if these also get flagged misspellings?
