Add mass resolution variables for intermediates

Include these variables in the dumped ntuple (for k-factor

Frankenstein refit settings

The refit was originally meant for cleaner true 4-momenta.  Re-purpose
this to treat mis-id'd intermediate particles (D/Λc/etc → Ds).  So
currently change the refit setup as follows:

  - Mother: keep consistent with truth; the event did pass event
    selection, so LHCb thought it was a Bs.
  - Daughter1: first daughter is an intermediate state, so misid is
    complicated, not a simple misassignment of mass.  LHCb refits
    respective 4-momenta.  Emulate this by refitting with Ds mass
    constraints.
  - Daughter2: bachelor particle; simple misid here.  Keep consistent
    with truth, handled later as LHCb would: assign wrong mass keeping
    3-momentum unaltered.

NB: This is experimental and gives biased mass resolution (in favour of
LHCb reco).  For plots, see (Bd → DK, Λb → ΛcK, etc):

Update path to ntuples for local setup
Revert "Frankenstein refit settings"

This reverts commit 2ade4637b203717c5e094d878915ba173f91bbcb.

The rationale is: we see a bias in the mass resolution for the emulated
reco of the order of 20 MeV (latest templates show 50 MeV!).  This is
40% of LHCb mass resolution: ~50 MeV.  The k-factor varies by 2-4%.  So
in the worst case it is a 2-4% change in k-factor.  The affected modes
(where the "Ds" is not a real Ds) contribute little to the yields (<5%),
so overall effect should be very small.
