## Add DecFiles for Exotica decays involving Dark Matter

Hi, I'm adding some DecFiles for quite a few decays mode for exotica searches of Dark Matter, with different Dark Matter mass hypothesis.

It is important to know that two pairs of the decay modes share all of its flags for the event number, and there are more of 10 of them. The way I solved this is by changing the number of stable particles in the final state of one of the pair of decays modes to 9, since it is quite improbable that anyone want to use that event number.

The two decay modes pairs are:

`B_{s2}^{*0} \rightarrow K^{-}B^+(\rightarrow \Lambda_{c}(2505)^{+})`

,

`B_{s2}^{*0} \rightarrow K^{-}B^+(\rightarrow \Xi_{c}^{*+})`

(This is the one with the stable particle flag = 9)

and

`\Sigma_{b}^{*-} \rightarrow \pi^{-}\Lambda_{b}^{0} \rightarrow D^{-}K^{+}`

,

`\Sigma_{b}^{*-} \rightarrow \pi^{-}\Lambda_{b}^{0} \rightarrow D^{-}\pi^{+}`

(This is the one with the stable particle flag = 9)
