Add support for hierarchical time series

GregorDeCillia commented 5 years ago

As discussed with @alexkowa and @merangelik, it would be a good idea to add a class for hierarchical time series.

[x] Add support for the class to contain several tramoseatsSingle and x13Single objects
[x] Add a method addAggregate() to define weighted aggregates between the *Single objects
[x] Implement a run() method that performs a direct and indirect adjustment
[ ] Implement diagnostic methods to compare the direct and indirect versions
[x] plot() method

All this work should be done within the current polymorphic structure by introducing a new class persephoneSingle.

persephone
  ├─ persephoneSingle
  │    ├─ tramoseatsSingle
  │    └─ x13Single
  └─ hierarchicalTimeseries

About the missing TODO

of this issue: We should check out https://github.com/djhurio/SA-indirect-quality and possibly contact the author about reusing some functionalities of that package.
