Type definition of `numbers` is incorrect

[luc122c]

This type definition is incorrect:

currency-codes/index.d.ts

Line 18 in 6de7fe6

export function numbers(): number[];

The 'number' field in data is a string. There are two solutions to this:

1. Update the definition to string[]
2. Pass the value through the number constructor to make it a number

I'd be happy to open a PR for whichever solution is prefered. Personally, I'd prefer number to be an array of numbers :)

Option 1 is correct even though it's not exactly intuitive. ISO-4217 includes many "numeric code" values with leading zeros such as 008 (Albanian Lek, ALL) and 032 (Argentine peso, ARS) among many others. The name for this field is unfortunate, given it does not reflect the type of value it contains.
