Problem in error comunication between listener and device makes the ethoscope crash

[ggilestro]

The earlier commit that created two services did not handle well how errors propagate between the two whenever the raise statement is used.

Two examples to reproduce this are 1) when the ethoscope_listener service raises an issue when three targets cannot be found, the system hangs.

https://github.com/gilestrolab/ethoscope/blob/666c6dae12d88d534fe3367c9ada965f2082b79c/src/ethoscope/roi_builders/target_roi_builder.py#L177-L180

2) when a problem occurs during image acquisition.

https://github.com/gilestrolab/ethoscope/blob/666c6dae12d88d534fe3367c9ada965f2082b79c/src/ethoscope/hardware/input/cameras.py#L252-L253

In both cases, ethoscope_listener should raise the problem so that ethoscope_device can show it and both should continue.
