We want to deprecate the finance.maskedNumber() method for removal.

Reasons for removal

• The method has/had a bug for 6 months and it hasn't been reported at all -> low/no actual usage.
• Configuring the method is more time and code consuming than just adding the parenthesis and ellipsis manually instead.
• There is no real standard for anonymizing these data. Developers will likely have their own anonymizing function that they use for their actual data.
• The way the data are anonymized is very specific, in most cases the data are replaced by * instead of being outright removed.
• There are way more data that you might want to mask such as e-mails, ibans, credit card numbers, that cannot be generated by the method.

Suggested workaround

const data = faker.finance.iban(); // "DE31070946979005090431"
const maskedData = data.replace(/(?<=.{4})\w(?=.{2})/g, '*'); // "DE31****************31"
