Adding FT flag for some RD lines

This MR aims to included the flavour tagging information on some of the lines of the RD wg. This lines will also be tracked in the following issue: #644 (closed) .

DECAY	PURPOSE	Expected Delta BW (MDF method)
B^0 \rightarrow (\rho, \phi, p\bar{p}) \ell\ell HLT2 lines	FT	+11% over the total RD BW (x10 increase for the single lines)
B^0 \rightarrow (\rho, \phi, p\bar{p}) \ell\ell, H_b^0 \rightarrow h^+h^- \ell\ell Spruce lines	FT	+28% over the total RD BW (dominated by the inclusive 4 body)

Comments:

• Might consider to add B0ToKS0MuMu lines if !2888 (comment 7579958) is not done in time?
• For later: check if selections are problematic for TD analyses?
