+- Refactored the Netherlands Holiday provider by moving the calculation of individual holidays to private methods. This will reduce the complexity of the initialize method.

+- Changed the USA Provider to check all holidays for potential substitute holidays, not just New Year's Day, Independence Day, and Christmas Day. [\#140](https://github.com/azuyalabs/yasumi/pull/140) ([jagers](https://github.com/jagers))
+- Adjusted tests for the 'next' and 'previous' methods to avoid actually exceeding the year boundaries.
