If you have documentation from mastercard/maestro that indicates this bin range needs updating, we'll go ahead and make a change for better accuracy.

Hi, as I saw in the the another lib (https://www.npmjs.com/package/creditcards-types), sometimes test cards don't have a valid number to type conversion. I will be closing this as probably this is the case.
