publicsuffix.org's purpose is cookie security; as such, looking up the public suffix
of a direct public suffix is defined to return null (e.g. 's3.amazonaws.com')
for my use, I want only to know the VALUE of the public suffix, so null is bad
I added a method, .getPublicSuffix, which will compensate for this
Misunderstood 'tldExists', fixed getPublicSuffix to compensate

Added some tests for the new method `getPublicSuffix`

Conflicts:

Proper tests for `getPublicSuffix` and better implementation.
