style: move all events into a (separate) library?

[gosuto-inzasheru]

the approach that i had seeing for this to keep the actual contract as neat as possible, it is to create an interface for each of the contracts, say:

1. IRoboSaverVirtualModule.sol ->>> here all events are stored w/ their right natspec etc
2. Inherit that into RoboSaverVirtualModule.sol and will have all events inside automatically

that approach moves all this Ls to the interface basically
