Fixing bba (#31)

* Fits and error propagation in data analysis

* Streamlined and sped up the beam reach scan

* Removed unnecessary parameters, typically cuts

* Separated real and simulation-only observables

* Merged pseudoBBA and fake measurement functionality to fake_bba

* Adding BBA to tests

* Still some TODOs for later
