The number of CBC parameters is set based on the cmd options (so
data->NX is always initialized).

Move BayesCBC initialization to main BayesWave program and add
some print settings.

Move setup of BayesCBC that needs to be done before all independent
updates (to make sure BayesCBC is up to date about the latest
model parameters, projections, SN etc.) to subroutine.

Add optional tidal version cmd option (to determine how many semi-intrinsic
parameters are needed).
