Remove dependency on Hadoop

This pull request attempts to remove the dependency of the simulator on Apache Hadoop 
which is pulled in as a consequence of using parquet-mr. 
The reason for removal is that Apache Hadoop does not work natively on Windows 
without user intervention, which makes adoption on this platform more difficult.

* Add Windows as CI target for the OpenDC simulator
* Use `LocalInputFile` for Parquet reader usages
* Use `LocalOutputFile` for Parquet writer usages
* Remove Apache Hadoop as dependency of OpenDC.
