Option for NaN value for currency filter

[cs-jonas]

It would be nice to have an option to set the displayed value for NaN values.
Example:
{{ 1234 | currency('€', {nanValue: '-'}) }} --> '1234.00€'
{{ "NaN" | currency('€', {nanValue: '-'}) }} --> '-'

You can achieve the same result this way:

{{ value | currency('€') || '-' }}
