Update IWear Logger with rpc control to start new log session #118

Is your feature request related to a problem? Please describe.

The addition of new IWear Logger device is very handy in dumping wearable data form a wearable device to a .mat file. If I am not wrong the data dumping is continuous and multiple .mat files are created for the entire duration the yarprobotinterface is running. @prashanthr05 please correct me if I am wrong about this.

In some tests yesterday with the Paexo wearable device https://github.com/robotology/wearables/pull/117, we noticed this behaviour. So, for every new experiment we had to terminate the yarprobotinterface and start again for a new experiment.

Describe the solution you'd like

A nice additional feature that can improve the logging further is to have control over the logger to start a new acquisition through rpc control. This helps in logging multiple sessions that correspond to different experiments, without having to terminate and restart the wearable device through yarprobotinterface

Indeed that could be an useful feature.

We might have to be careful about creating a new folder for each acquisition trial by modifying the <experimentName> and <path> configuration parameters, so that all the relevant logs related to one acquisition gets stored in separate, respective folders.

Also we need to understand, how to reset the BufferManager (existing data across different channels). I guess, currently there's no option in yarp-telemetry to do so.
