Add malaysian itn number

[pokoli]

This PR implements what is described on #113

I did not found so much information of the number so it is based on:

http://www.oecd.org/tax/automatic-exchange/crs-implementation-and-assistance/tax-identification-numbers/Malaysia-TIN.pdf

I will complete the tests with all of the numbers of this source document plus a real number example which I am waiting to receive from some of our users.
