REGION_CODE_FOR_NON_GEO_ENTITY being removed from supportedRegions

[MB34]

I'm not sure if this package is still being supported because there haven't been any updates on issues since 2013. But...

In the init function, the call that removes the REGION_CODE_FOR_NON_GEO_ENTITY from the supportedRegions array removes US from the supportedRegions.

unset($this->supportedRegions[array_search(self::REGION_CODE_FOR_NON_GEO_ENTITY, $this->supportedRegions)]);

Why is this being done? It means that I cannot use this for US numbers.

I fixed it by replacing your init code with that by gissey's: https://github.com/giggsey/libphonenumber-for-php

But I'd really like to know why it was done this way and how to correctly use this package for US numbers.
