Adding time correction in dataset generation

[ayuberonavarro]

This update will allow to define a control variable available in the analysis tree. Only those time periods where the control variable fulfils certain conditions will be added to the dataset. The algorithm will take care of correcting the dataset run duration for the intermediate run removed periods.

• [x] Adds new method GetRunDuration that implements run correction using a given analysisTree variable.
• [x] Adds a dataset validation pipeline.

The dataset.rml is not present, to check that it is coherent with the code.

Inside pipeline/datasets/ there should be the validation macro and the rml.
