Manual: also add warning to the object documentation

- The [MCParticle](#mcparticle) that created the deposited charge

  ([`getMCParticle()`](https://allpix-squared.docs.cern.ch/reference/classes/classallpix_1_1depositedcharge/#function-getmcparticle))

{{% alert title="Warning" color="warning" %}}

It should be noted that in most cases, storage of DepositedCharge objects is not required. Since individual objects are

generated for every electron and hole in the event, storing them will lead to large output files and possible performance penalties.

For more details refer to the [code reference](https://allpix-squared.docs.cern.ch/reference/classes/classallpix_1_1depositedcharge/).

## PropagatedCharge

- `CarrierState::HALTED`:

  The motion of the charge carrier has stopped, for example because it has reached an implant or the sensor surface

It should be noted that in most cases, storage of PropagatedCharge objects is not required. Since individual objects are

generated for every electron and hole in the event, storing them will lead to large output files and possible performance penalties.
