Lib should error instead of stripping invalid characters

I found an issue where ‘123.sd’ is turned into ‘123.00’. I was expecting this to error out as it is not a valid currency value. Looking at the code I found the following test. Any insights of what is the logic of such functionality?

If the functionality has come valid case, would it be possible to have a flag that will make this case error out?

test('should strip invalid characters', t => {
  var str = currency('a1b2c3');
  t.is(parseFloat(str), 123, 'currency("a1b2c3") is 123');
});

@ericvera I think a having strictInput or strict mode actually sounds reasonable. I need to think about what that means in relation to errorOnInvalid but that’s something that could potentially be released with a 2.0 version of the library.

it’s v2.0.4 as of now, shouldn’t this be implemented?
