Sync & Accumulation: formalise Int/ExtTriggerMulti behaviors
Lima does not provide a formal interface for ExtTriggerMulti in Accumulation mode. The current implementation assumes that there will be as many external triggers as low-level frames. While this is one possible alternative, it is also desirable to perform a burst of internally-triggered frames per each received external pulse. A similar situation is found in IntTriggerMulti, where not every hardware supports burst of internally-triggered frames started by software.
The implementation might require the definition of a new parameter: nb of internal frames per trigger.
