Title: New currency costumizations possibilities

feat($filter): currency (currencySymbol, fractionSize, isMinus)

Added new costumization possibilities to currency:
- Fraction size
- Change default negative numbers parentheses to '-' minus symbol

Previous behavior remains the same but when using the new optional parameters, the currency symbol becomes obligatory.
