HV-808 Fixing Mod11 and CPF Validation Bug

- ModUtil#mod11 no longer validates the check digit, only calculates the checksum result

- ModUtil#passesMod11Test: Change the way validation test is done, compares check digit with sum mod instead of checking if the Mod11 sum of all elements returns 0, this fixes when the same check digit is used for 10 and 11. Adding explicit comment about the assumption the mod11 algorithm makes

- Change the method's signatures  of ModUtil#mod10 and ModUtil#passesMod11Test to use the check digit as a separate parameter

- ModCheckValidator Check digit is no longer passed on the same list with other digits of the code, but as a separate int value

- @CPF: Change exlusion patterns: Non-digit characters are now optional, Adds more exclusion patterns, any sequence of the same digit passes on the mod11 check but are considered invalid CPF numbers.
