Can you reduce the size of the Yoctopuce library?

There are ways to reduce the memory footprint of our library, but not to the point of reducing everything to a few manually forged USB packets. Let's look at it in detail.

Storing real-time measurements in a CSV file

Although Yoctopuce sensors have a built-in data logger, it is often useful to store the data in a database or CSV file for local processing. Ideally, one would like to fetch the data in real time as much as possible, but reserving the possibility to retrieve the data stored by the module in case of temporary connection loss. And this is not so difficult to do...
