v1.1 was released yesterday in preparation for USPS change coming in June

[VinceG]

@kennj2016 test what? when installing with composer just do composer require vinceg/usps-php-api:^1.0.4

@VinceG althought I downgraded to 1.0.4 but still get an error "Error: API Authorization failure. ExpressMailLabel is not a valid API name for this protocol."
