PWGCF: bug fixes in femtodream (#2735)

* Feat: add |eta| cut to V0s

* Feat: add automatice systematic variations to cutculator

* Fix: fix debug tasks

* Fix: fix naming of femtodream tables

For the o2-aod-merger to work on merging derived data generated by the
femtodream-producer task the naming of table have to follow the naming
conventions of the O2 framework.

* Fix: fix order of includes

* Fix: fix copyright headers

* Revert "Fix: fix copyright headers"

This reverts commit 09a0db6.

* Fix: fix copyright headers

* Fix: use consistent headers

* Update FemtoDerived.h

Removed data model commented code
